Merge pull request #260 from efabless/fix_top_buffers_again 
More changes to the GPIO buffer cell
 2022-10-17 03:35:25 +02:00
Tim Edwards 9f54b2ecec Added a gate-level version of gpio_signal_buffering derived from 
the RTL, but cleaned up for macro definitions;  this can be used
for LVS.  The decap cells were hand-edited in because there is
no way to devine them from the RTL source.
 2022-10-16 21:20:12 -04:00
Tim Edwards 69d353f65c Corrected the verilog and the layout for the caravan version of the 
signal buffering (verilog was missing one of the buffers, and the
layout had some of the labels at the top accidentally erased).

M0stafaRady 8526aadd4a Revert "remove unpowered netlist" 
This reverts commit dd482cb099.
 2022-10-16 09:56:24 -07:00
Tim Edwards c5e7c67d60 Once again. . . Rewrote the RTL verilog so that only signals 
being buffered pass through the buffer macros.  Removed the
straight-through signals from the layout, and renumbered the
vectors in the buffer cells, which no longer match the numbering
at the top level (unfortunately).

Tim Edwards ac209d2397 Corrected a bunch of typos (different signal names used in the 
same file), errors (buffer output pin name, power supplies not
passed at the top level).  Corrected a major error that prevented
the use of the buffers in simulation, so this was not previously
verified by simulation.  The buffering has now been properly
verified.

Tim Edwards f7ec0cd012 Added buffers to the top level, inside a macro called 
gpio_signal_buffering (gpio_signal_buffering_alt in caravan).
Note that this macro requires manual placement and routing, like
the padframe, and the top level will need to route around its own
internal routes.
