tangxifan ff7ea99381 bug fixed in register scan-chain architecture 2020-04-07 17:06:16 -06:00
tangxifan 2342d7cdc6 minor tweak on the scan-chain support in VPR8 as well as architecture file
Do NOT use pack patterns for the scan-chain. It will cause searching root chain in VPR8 to fail
Actually, we do not use scan-chain in mapping designs. Disable the pack pattern has no impact

tangxifan 8a996ceae5 bug fixed in tileable routing when heterogeneous blocks are considered;
VPR have special rules in checking the coordinates of SOURCE and SINK nodes,
which is very different from the OPIN and IPIN nodes
Show respect to it here.
