VSD - Embedded-UVM

Of course, there is a requirement for open-source verification, but that’s not the only thing we want to cater to. There are other verification trends and challenges which system Verilog and other verification platforms are not able to meet. So, we want to position Embedded-UVM for that. In the past decade or so, the major thing which is making verification tougher than it used to be, is the death of Moore’s law.

As far as processor frequency goes, it stabilizes at 4GHz and it's coming down as we move to multi-core processors. So, when you look at it from a simulation perspective, post-2005 it is becoming increasingly difficult to run simulations on bigger chips.

Chip size keeps increasing, while processor speed is stagnant and hence, simulation is a limiting factor. Simulation speed is going to be limited unless we move to multi-core processors. Contemporary EDA tools run RTL simulations in a multi-core environment. System Verilog doesn’t run in a multi-core environment.

Therefore, test-bench runs on one thread and RTL runs on multiple threads. RTL is more formal in nature, in sense, it can be synthesized, it can be partitioned, different partitions can run on different processors, while test-bench is behavioral in nature and it cannot be partitioned the way RTL can be.
