Matt Guthaus 49bee6a96e Remove OEB signal since we split DIN/DOUT ports 2018-08-13 14:09:49 -07:00
Matt Guthaus a7a3099702 Fix comments in stimulus file to show list and not zip type 2018-07-27 15:00:00 -07:00
Matt Guthaus 71606e1097 Add read cycle to clear DOUT bus before each read measure. 2018-07-27 14:06:59 -07:00
Matt Guthaus 8f72621f4a Converted delay measurement to use add_read/add_write functions. 
Rewrote the logic to add one cycle at a time for easier
manipulation. This can be extended more easily into the
functional simulations.

Matt Guthaus a00e160274 Convert bitline index to integer in trim_spice 2018-07-26 14:29:44 -07:00
Matt Guthaus bc67ad5ead Fixed timing to be measured from positive clock edge since 
reading a 1 will be the precharge time.
Started modifying the lib file for DIN and DOUT ports, but did not
check the syntax yet.
 2018-07-26 13:58:50 -07:00
Matt Guthaus 00a87d57ab Modified pinvbuf to have a stage effort of 4 for driving the 
clock bar to wordline enable.
Fixed comments in stimulus file to have right cycle numbers.
Removed clock gating on we signal since clock gating is already
done on the WL signals. It is redundant.
