|\ | | | | interchange: Disambiguate cell and bel pins when creating Vcc ties
| * interchange: Disambiguate cell and bel pins when creating Vcc tiesgatecat2021-04-091-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | The pins created for tieing to Vcc were being named after the bel pin, relying on the fact that Xilinx names cell and bel pins differently for LUTs. This isn't true for Nexus devices which uses the same names for both, and was causing a failure as a result. This uses a "PHYS_" prefix that's highly unlikely to appear in a cell pin name to disambiguate. Signed-off-by: gatecat <gatecat@ds0.me>

| * [interchange] Prevent site router from generating incorrect LUTs.Keith Rothman2021-04-063-42/+102
| | | | | | | | | | | | | | | | | | The previous logic tied LUT input pins to VCC if a wire was unplacable. This missed a case where the net was present to the input of the LUT, but a wire was still not legal. This case is now prevented by tying the output of the LUT to an unused net.

| | | | | | | | | | | | | | Previous pseudo pips were the same cost as regular pips, but this is definitely too fast, and meant that the router was prefering them. Signed-off-by: Keith Rothman <537074+litghost@users.noreply.github.com>

| * Fix bug in router2 where router may give up too early.Keith Rothman2021-04-061-1/+13
|/ | | | | | | | | | Was introduced in #612. The logic before was intended to prevent the router from terminating early when not using a bounding box, but the fix in #612 simply removed that, meaning that the router might terminate early incorrectly. The solution here is to only use the toexplore hysteric once a solution is found. Signed-off-by: Keith Rothman <537074+litghost@users.noreply.github.com>
