mguthaus 04ed3792c7 Fix analytical lib tests with new power numbers. 2018-03-02 18:13:06 -08:00
Michael Timothy Grimes 4d3f01ff2f The bitcell currently passes DRC and LVS for FreePDK45 and SCMOS 
There are 2 benchtests for the bitcell:
1) one with 2 write ports and 2 read ports
2) one with 2 write ports and 0 read ports
The second test is meant to show how the bitcell functions when read/write ports are
used instead of separate ports for read and write
The bitcell currently passes both tests in both technologies
Certain sizing optimizations still need to be done on the bitcell
