"""
|
|
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!
