To Emulate or Prototype?

Monday, May 23rd, 2016

Emulation-or-PrototypingRecently I read a Semiwiki article, Army of Engineers on Site Only Masks Weakness, in which author Jean-Marie Brunet of Mentor Graphics wrote that FPGA Prototyping requires an army of tech support engineers on-site to mask the weaknesses of FPGA prototyping flows. As the Tech Support Manager for Aldec Hardware Emulation Solutions, I have to admit I’ve never had to deploy an army onsite.

It is true that FPGA Prototyping is more challenging than emulation. Yet, for the time invested in prototype setup, developers are rewarded with a validation platform that is capable of running orders of magnitude faster than emulation.

Acceleration-Ready UVM Webinar with Doulos and Aldec

Wednesday, April 6th, 2016

doulos_logo

Doulos CTO, John Aynsley, and I will be presenting a free 1 hour training  webinar, Acceleration-Ready UVM, on Wednesday April 13th, 2016. Learn more in this guest blog by John Aynsley, excerpted from the Aldec Design and Verification Blog.

Acceleration-Ready UVM 

by Doulos CTO, John Aynsley

We hear that emulation is one of the fastest-growing segments in EDA right now, yet simulation still continues to be the main workhorse for functional verification, and SystemVerilog and UVM are everywhere you look. But how do you combine the two? How do you run a UVM-based constrained random verification environment alongside an emulator and get reasonable execution speed?

 

Many vendors have solutions, including Aldec with their HES-DVM™ emulator. Their solution is based on the Accellera SCE-MI standard, and in particular on SV-Connect, which is a function-based interface that uses the SystemVerilog DPI (Direct Programming Interface) to pass information between the host and the emulator. You partition your UVM drivers and monitors into two parts, a small proxy that remains on the host and a synthesizable implementation that goes into the emulator. That way, all of the low-level timing detail is removed from the UVM code running on the host and is placed in the emulator, where it belongs. The communication between the host and the emulator can be optimized to avoid the emulator being stalled while waiting for the slower UVM simulation running on the host.

‘UVM Really is Everywhere’ at DVCon Europe

Wednesday, November 4th, 2015
Next week, Aldec will join other top tier organizations as a proud Silver Sponsor at DVCon Europe 2015 in Munich, Germany. There our team will offer live demonstrations of hardware-assisted verification of UVM following Doulos Ltd.’s Easier UVM guidelines. Alex Grove of Aldec will also deliver a DVCon Europe tutorial, ‘UVM Hardware Assisted Acceleration with FPGA Co-emulation’.

Emulation: Thinking outside of the Big Box

Tuesday, September 22nd, 2015
 
fpga_base_emulation_bIndependent FPGA Consultant, Doug Amos, has been working in programmable logic and FPGA for over 30 years. He did his first programmable logic design in the mid-80’s (around the time Aldec was born), and since then has designed or supported countless FPGA and ASIC designs.
We’ve been pleased to work with Doug over the past several months, to help tell the story of Aldec’s advanced hardware emulation and SoC and ASIC prototyping solutions. Here is a excerpt from Doug’s recent guest blog:

There’s no question; verification is a massive time drain in SoC and other chip design projects. For many years, those with deep enough pockets have turned to so-called “Big Box” emulators in order to recover some of the time lost on RTL simulation, but what about the rest of us? Is there another way to accelerate verification and reduce our overall project schedule? Yes there is; and at Aldec they call it FPGA-based Emulation.

“FPGAs; aren’t they just for prototyping?”

Sure, FPGAs are the fastest platform for prototyping, but we can also harness that speed into our verification environment, then we can achieve runtime performance 2x to 5x faster than traditional “big box” emulation systems, and all at a fraction of the cost per gate per MHz. The most significant differences between FPGA usage in prototypes and in emulation is shown in table 1.

How HES™ Technology Solved Problems for These Users

Monday, October 20th, 2014

HES_USE_CASESRecognizing a problem that engineers are facing and developing a solution has been Aldec’s rather straight-forward mantra for going on thirty years now. Aldec launched its Hardware Emulation Solutions (HES) product in 2003, integrating RTL simulation with hardware emulation, and offering hardware and software design teams the ability to work concurrently. Today HES™ is a fully automated and scriptable HybridVerification and Validation environment for SoC and ASIC designs capable of bit-level simulation acceleration, SCE-MI 2.1 transaction emulation, hardware prototyping, and virtual modeling.

FPGA-Based Prototyping Q&A: 100 Million Gates and Beyond

Wednesday, July 30th, 2014

live-aldec-webinar

I am a Hardware Technical Support Manager. Ask Me Anything!

Earlier this summer, I joined a team traveling from Aldec’s R&D offices in Kraków, Poland to attend the annual Design Automation Conference (DAC) in San Francisco. As Technical Support Manager for Aldec’s Hardware Products Division, my goals for this event were two-fold. First, as we’ve made huge enhancements to our HES-7™ FPGA prototyping solution in the past year, I wanted to be there in person to share more about them in demos and presentations at the Aldec booth.

Secondly, and really my favorite part of DAC, I wanted to hear from engineers in the field looking for solutions to their real-world problems. Sometimes I have immediate answers for their questions, like the engineer who was not happy with their current solution’s implementation time or the fellow that needed support for in-house development boards. Occasionally though, I don’t have an immediate answer and instead they’ve given me valuable ideas that I get to take back home to my team so we can set to work developing solutions.
