Hunter Nichols 16e658726e When determining bitline names, added a technology check for sky130. 2021-06-16 17:04:02 -07:00
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 c472a94f1e Rework bitcells. 
Name them 1port and 2port consistently.
Allow cell overrides to cell_1rw and cell_2rw or other.
Will use 2rw for 1rw/1r, 2rw, 1w/1r, etc.
