Matt Guthaus 6963a1092f Make bitcell width/height not static. Update modules to use it for pbitcell. 2018-09-04 11:55:22 -07:00
Matt Guthaus 6401cbf2a6 Move place function to instance class rather than hierarchy. 2018-08-27 17:25:39 -07:00

mode is enabled.

Matt Guthaus 19d46f5954 Finalized separation of netlist/layout creation. 2018-08-27 14:18:32 -07:00
Matt Guthaus e827c1b8c7 Make pinvbuf have unique names for GDS compliance.
Add back gating of w_en since write should happen in second half
or else we will have write and precharge simultaneously active.

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.

Matt Guthaus 97c08bce95 Add dffs to control logic. Rename layout pin segment/rect functions for consistency. Redo gnd/vdd pins in control.
Shift s_en buffers even with other cells.

Matt Guthaus 696433b1ec Add bank_sel to bank_select module as input.
Remove reference to control in sram.
Add dff_buf_array to options.
Added inverted DFF
Add variable height pinvbuf

Matt Guthaus bab92fcf38 Rework hierarchical decoder to not be folded. Remove address from central bank bus and access via side pins now. Eight way column mux now works. 2018-03-23 08:13:20 -07:00
Matt Guthaus ed8eaed54f Reworking control logic for veritcal poly. Rewrote delay line. Rewrote buffered-DFF array. 2018-03-23 08:12:47 -07:00
