What is the relation between pyvsc and portable stimulus (pss)? about pyvsc HOT 2 OPEN

Hi @davidmlw,
The short answer is "No". PyVSC provides data randomization and functional coverage collection, with similar constructs to SystemVerilog. PyVSC is a good choice if you use a Python-based simulation testbench methodology (eg cocotb, pyuvm) and want to do constrained randomization and collect functional coverage.
PSS is a language that targets modeling and generation of system-level tests -- for example, bare-metal software-driven tests for SoC-integration testing
PSS also has data randomization and functional coverage collection, but adds on top:
- Actor Model-style capture of scenarios that incorporate constraints over time
- Language constructs for modeling system-level resource contention and dataflow
- Language constructs for modeling multi-core scenarios
- A well-defined path to create efficient software-driven tests

I recently wrote a few blog posts as an introduction to some of the core features and capabilities of the PSS language. If you're interested, please have a read:

Many thanks. Very good blogs!

What is the status and acceptence of cocotb, pyuvm and pyvsc? I see a big opportunity for python in verification, and I think they perfectly fit the verification tasks without legacy VIP dependencies.

What would you suggest if adopt cocotb, pyuvm and pyvsc in production?
