mrg 5843aa037c Update functional test to use spare columns separately. 
Fix no spare columns data width error.
 2021-04-07 16:08:24 -07:00
mrg 0a02f635ad Remove lvs_write from sram 2021-04-07 16:08:24 -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.
