Michael Timothy Grimes 19ca0d6c2a Changing control logic names to match naming scheme for multi-port. din[0] to din0[0], s_en to s_en0, addr[0] to addr0[0], etc. Sram level should pass unit tests for single port but will not currently pass for multi-port 2018-08-18 16:51:21 -07:00

Matt Guthaus 7c254d540d Change channel route api to use pin maps instead of an insteads for cases where there are multiple instances that have the pins (e.g. decoders) 2018-07-25 11:37:06 -07:00
Matt Guthaus f7a2766c29 First draft of naive channel route in hierarchy_layout. It doesn't implement horizontal conflicts or try to minimize the number of channels. 2018-07-25 11:13:30 -07:00

Matt Guthaus f3ae29fe0b Getting single bank to work reliably. Removed tri_gate from bank
for now. Will add it in multibank arrays only. Not needed for
separate DIN and DOUT ports.
