mrg d609e4ea04 Reimplement trim options (except on unit tests). 
Allow trim netlist to be used for delay and functional simulation.
Each class implements a "trim_insts" set of instances that can be removed.
By default far left, right, top and bottom cells in the bitcell arrays are kept.

Use lvs option in sp_write

Fix lvs option in sram.

mrg c7f99aef2c Add functional comment to aid debugging checks. 2021-03-31 12:14:20 -07:00
mrg 671470f5f2 Skywater changes. 
Default 1 thread and no temp subdirectory.
Add skywater setup/hold golden data
Add CLI option for simulation threads (-m)
Add compatibility mode option and nomodcheck for ngspice to speed up sky130 model loading.
Make subdir when using default /tmp dir.
Pass num_threads so temp subdirs are created.
