OpenRAM/compiler/verify.py

"""
This is a module that will import the correct DRC/LVS/PEX 
module based on what tools are found. It is a layer of indirection
to enable multiple verification tool support.

Each DRC/LVS/PEX tool should implement the functions run_drc, run_lvs, and
run_pex, repsectively. If there is an error, they should abort and report the errors.
If not, OpenRAM will continue as if nothing happened!
