Simulation tool for verilogA model? #17

Open ratul619 opened 3 years ago

ratul619 commented 3 years ago

Hi,

I am trying to simulate the verilogA model - which open source tool(s) would you suggest to dump waveforms ?

Thanks

Xyce -- see also #10

From @QuantamHD;

$ buildxyceplugin -o rram2 rram2.va . && Xyce -plugin ../../sp_lib/rram2.so rram_test.spice

@ratul619

Xyce if you need to simulate the device itself, but if you're asking for tools to view the waveforms. I've heard nice things about gtkwave, and mathplotlib which is just a python library that you can easily use to view waveforms.

FYi - There are some examples of spice simulations which produce data and svg at https://cs.opensource.google/skywater-pdk/sky130_fd_pr/+/main:cells/npn_11v0/tests/

I am unsure were the code that runs the spice simulation has ended up.
