manarabdelaty 8b1c5df909 [DATA] Update caravel_clocking module (timing clean) 2021-11-25 15:23:01 +02:00
Tim Edwards be98da0fe6 Added spare logic block to caravel layout and verilog GL, wired
it to the power supply, and checked top-level LVS.

Tim Edwards 08a2c90940 Made updates to correct LVS errors in caravan. Found one major error in the RTL
verilog for both caravel and caravan.  Hand-edited the RTL and GL netlists to
correct this;  still need to correct the layouts.  The error causes the user1
side clock, load, and reset buffers to drive the user2 side as well as the user1
side, making a huge mess of the routing.  Will route this by hand.

Tim Edwards 515b5a54f2 Updates for LVS. Only LVS issue remaining for caravel is how to get the
ground domains to extract independently.

Tim Edwards 6eb8bb54de Several more LVS corrections, including fixing a label in chip_io that
got removed from its net by a chang in the LEF view of an I/O pad, and
a lack of declaration of an array to attach to pwr_ctrl_out in the
verilog, which is valid verilog but netgen can't know the bus size
without the no-connect net being declared.  The remaining issue has to
do with separation of ground domains in the mgmt_protect block.
