Michael Timothy Grimes 820a8440c9 adding unit test for bitcell array using pbitcell 2018-03-06 16:36:11 -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

Michael Timothy Grimes b90f5c9a59 pbitcell is now a multiport cell with a read transistor that connects to RBL and RROW and a read access transistor that connects to Q and gnd
current commit works without drc errors on freepdk45 but has drc rules not included in scn3me_subm. Does have lvs errors
adding several unit tests: the basic one that tests the full functionality of the pbitcell, one with no write ports, and one with no read ports

Michael Timothy Grimes 64e7ed5b5e Adding pbitcell.py: a multiport bitcell with a variable number of write ports and read ports
Adding 04_pbitcell_test.py: The benchtest for pbitcell

Mostly done. Layout nearly complete with the exception of the well contacts and a connection between the gates of the read
transistors and their corresponding vias. Then several drc corrections need to be made.
