How to Design the New Generation of Reprogrammable Router/Switch Using Zynq FPGA

Thursday, January 25th, 2018

A high-performance router is an absolute must if you want to run a high-traffic network in which different devices need to transfer and receive data as fast as possible. A router with a powerful processor and sufficient local memory reduces data hiccups and minimizes message loading and buffering times. But is that enough?

Because of the huge amount of data that people now generate – combined with the wealth of communication protocols, such as Wi-Fi, Ethernet, USB, SFP, QSFP – high-performance, hardware re-programmable routers are becoming popular. That hardware re-programmability is being delivered through FPGAs, and utilizing one as the main ‘processor’ on the router makes it easy to add or modify desired modules such as encryption and compression.

Partition your Design for FPGA Prototyping

Monday, December 11th, 2017

Modern ASIC and SoC designs have increased in complexity such that multiple FPGAs of the largest capacity are now required to prototype the entire functionality of the design. As design sizes increase, more and more FPGAs are required. The capacity and pin limitations of FPGAs create constraints for how the ASIC/SoC design can be mapped into the FPGAs. Aldec’s HES-DVM’s prototyping mode accounts for the limitations of the target FPGAs and allows the user to map a design to the FPGAs within these constraints.

Partitioning a design to fit into multiple FPGAs can be a lot of work

Designing the partitions with HES-DVM is as easy as selecting specific VHDL/SystemVerilog design modules from the hierarchy and moving them to a desired partition. All information about the design modules and the amount of LUTs, Flip-flops, memory blocks, DSP slices, and I/O consumed are displayed for convenience. These values can also be viewed as a percentage of the target FPGAs’ available resources allowing you to know when an FPGA is full.

Adding a module to a partition

Mapping a partition to an FPGA

Once the partitions are finalized, each partition can be assigned to a specific FPGA. A design successfully fitting into the FPGAs on the target prototyping board is only the beginning. There still remains a big problem with the sheer number of connections between the partitions. Modern designs have thousands of internal signals interconnecting major blocks or sub-systems. It’s likely that there won’t be a sufficient amount of direct connections between FPGAs to support the design’s internal wiring. How can the large amount of internal design signals possibly be accommodated by the relatively smaller amount of I/O available from the FPGAs?

Zynq-based Embedded Development Kit for University Programs

Tuesday, October 17th, 2017

Creativity and innovation, which lead the society to success, rest on the foundational institutions such as schools and universities. They provide fertile soil to seed, grow and flourish enterprises. To harvest more within an industry, the ecosystem needs to be enriched where the seeds are grown. Considering that the university’s courses are the nutrition to student, they need to be designed in a productive manner as they will provide the next generation of engineers. By providing the necessary platform in addition to the rich and informative tutorials, the quality of the input information for students would be assured. Particularly in the field of Electrical and Computer Engineering, it is important that students get as much hands on experience as possible, and tackle design challenges – such as HW/SW co-design and co-verification – before entering the job market; for their own benefit as well as the industry as a whole.

In this blog, you will become familiar with the TySOM Education kit (TySOM EDU) package designed for the university courses related to hardware design and embedded system design researches.

The TySOM EDU contains a TySOM embedded development board, Riviera-PRO advanced hardware simulator and informative tutorials and reference designs. Although it is possible to choose any development board from the TySOM embedded development board family, the TySOM-1A-7Z010 would be the most cost-effective solution for most university projects.

TySOM-1A-7Z010 (ZynqTM) is a ready-to-use and feature-rich embedded development board which provides the required peripherals to tackle both basic and advanced Zynq-based projects. The XC7Z010 is based on the Xilinx® All Programmable System-on-Chip (SoC) architecture, which integrates a dual-core ARM Cortex-A9 processor with Xilinx 7-series Field Programmable Gate Array (FPGA) logic. Coupling the device to a rich set of peripherals for connectivity, communication and multimedia, makes this board ideal for university projects requiring HW/SW co-design.  For the rest of this article, visit the Aldec Design and Verification Blog.

Demystifying AXI Interconnection for Zynq SoC FPGA

Thursday, September 14th, 2017

Imagine traveling back in the time to the early human ages. It’s going to be both scary and interesting when you meet a person who probably cannot speak or if they do you won’t be able to understand them. Clearly, communication will not be possible until you find a mutual way to convey your respective meanings/intentions. The same principle applies in the world of electronics as there are various types of interfaces among electronic devices. Therefore, a standard communication protocol eases the transformation of data in a system, especially in a System-on-Chip (SoC) system which consists of different systems.

SoC FPGAs such as Xilinx® Zynq™ establishes the ARM Advanced Microcontroller Bus Architecture (AMBA) as the on-chip interconnection standard to connect and manage the functional blocks within the SoC design. The Advanced eXtensible Interface (AXI) is designed for FPGAs based on AMBA as a protocol for communication between blocks of IP.

Software Driven Test of FPGA Prototype: Use Development Software to Drive Your DUT on an FPGA Prototyping Platform

Monday, April 10th, 2017

on chip analyzerMost everyone would agree how important FPGA prototyping is to test and validate an IP, sub-system, or a complete SoC design. Before the design is taped-out it can be validated at speeds near real operating conditions with physical peripherals and devices connected to it instead of simulation models. At the same time, these designs are not purely hardware, but these days incorporate a significant amount of the software stack and so co-verification of hardware and software is put at high importance among other requirements in the verification plan.

 

However, preparing a robust FPGA prototype is not a trivial task. It requires strong hardware skills and spending a lot of time in the lab to configure and interconnect all required peripheral devices with an FPGA base board. Even more difficult is to create a comprehensive test scenario which contains procedures to configure various peripherals. Programming hundreds of registers in proper sequence and then reacting on events, interrupts, and checking status registers is a complex process. The task which is straightforward during simulation, where full control over design is assured, becomes extremely hard to implement in an FPGA prototype. Facing this challenge, verification engineers often connect a microprocessor or microcontroller daughter card to the main FPGA board. The IP or SoC subsystem you are designing will be connected with some kind of CPU anyhow, so this way seems natural. Having a CPU connected to the design implemented in an FPGA facilitates creating programmatically reconfigurable test scenarios and enables test automation. Moreover, the work of software developers can be now reused as the software stack with device drivers can become a part of the initialization procedure in the hardware test.. The software can become a part of the initialization procedure in the hardware test. If that makes sense to you, then why not use an FPGA board that has all you need – both FPGA and the CPU?

Aldec and NEC reveal HLS shortcut at upcoming SoC Conference

Friday, October 18th, 2013

The University of California, Irvine (UCI) is popular for many things, but I recall during my school days that it was distinctly known among students for its underground tunnel network. The official story is that they were simply built to house heating and cooling pipes. Yet, the rumor persists that this complex maze of underground tunnels was constructed decades ago to provide safe passage for faculty members in case of student riots.

I’ll admit I would love to uncover these tunnels someday, unfortunately they have long been sealed off from curiosity seekers. I will, however, be at the UCI campus next week unraveling a different sort of maze for engineers attending the annual International SoC Conference. Aldec is once again a Platinum Sponsor for this popular academic conference, and this year I will be joined by NEC Corporation’s Dr. Wakabayashi to present a technical session:

Integrating SystemVerilog and SCE-MI for Faster Emulation Speed

Wednesday, October 9th, 2013

In the last SCE-MI article, we discussed how SCE-MI macro-based infrastructures can speedup SoC design verification time. In SCE-MI 2.1, Accelera introduced a ‘function-based’ infrastructure which is based on SystemVerilog DPI functionality. The SystemVerilog DPI is an interface which can be used to connect SystemVerilog files with foreign languages (C, C++, SystemC, etc).

SCE-MI for SoC Verification

Wednesday, September 18th, 2013

Today’s System-on-Chip verification teams are moving up in the levels of abstraction to increase the degree of coverage in the system design. As designs grow larger, we start to see an increase in test time within our HDL simulations. Engineers can utilize Hardware-Assisted approaches such as simulation acceleration, transaction-level co-emulation, and prototyping to combat the growing simulation times of an RTL simulator. In this article, we’ll dive much deeper into the transaction-level co-emulation methodology.

The WHAT is mandatory but the HOW is entirely optional

Monday, September 9th, 2013

You look confused. Perhaps I owe you an explanation. Anyone familiar with hardware design flow knows that it starts with specification and ends with implementation. The specification in this flow is the “What” – it defines what needs to be designed. The process for implementation is the “How” – it defines how you are going to achieve it.

Let’s break down just one part of the “How” or implementation – the Design Process. For many years hand-coded RTL has been used as the de facto method for implementation and it is still being used as predominant method for designing cutting-edge hardware. But does it follow that it is the most efficient method? I would say probably not, especially given the ever-growing complexity of the hardware.
