This is a small and seemingly trivial post, but it’s a really big deal for me (and I assume others in the DV world). Verilator can compile and run UVM!

Building the latest and greatest Link to heading

This seems like cutting edge work with more things going in every day, so we need to compile verilator github.

git clone https://github.com/verilator/verilator
autoconf
./configure --prefix=`pwd`/build
make install

Running the example Link to heading

There is a small example in the Verilator tree. I still need to look at uvm_pkg_all_v2020_3_1_nodpi in more depth, but I assume there are some hacks from mainstream UVM. Well, it says no DPI, that may be a hint :)

verilator --binary -j 0 \              
  --CFLAGS -O0 \
  -Wall \
  +incdir+test_regress/t/uvm \
  test_regress/t/uvm/uvm_pkg_all_v2020_3_1_nodpi.svh \
  test_regress/t/t_uvm_hello.v

Hooray!
