Understanding the inner workings of UVM – Part 2

Monday, January 29th, 2018

In this blog, my major focus is on explaining the concepts such as Sequence, Sequencer, Driver and showing how the communication takes place from sequence to sequencer and from sequencer to driver. In the previous blog, I included a top-level diagram of the UVM structure, showing different base classes. If you need refresh your memory on where the classes Sequence, Sequencer and Drivers stand please click–understanding-the-inner-workings-of-uvm.

So, let’s look at the main concepts and follow the communication mechanism they use for the effective execution of a test.

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.
