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 e86831b188 Final edits to make caravel LVS clean. 2021-11-22 16:51:35 -05:00
Tim Edwards cd68a2aeff Made several corrections to errors found in the netlists: (1)
Fixed rstb_h, which was being input to low-voltage blocks.  (2)
Fixed flash_csb_ieb_core and flash_clk_ieb_core, which were not
output from housekeeping as they should be;  the solution was
to tie the INP_DIS lines low at the pad by connecting them to
the TIE_LO_ESD line.  This should probably be addressed in
housekeeping but would change the current pinout.
