|\ | | | | gowin: bugfix and improved clock router
| * gowin: improve clock wire routingYRabbit2022-12-305-45/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The dedicated router for clock wires now understands not only the IO pins but also the rPLL outputs as clock sources. This simple router sets an optimal route, so it is now the default router. It can be disabled with the --disable-globals command line flag if desired, but this is not recommended due to possible clock skew. Still for GW1N-4C there is no good router for clock wires as there external quartz resonator is connected via PLL. Signed-off-by: YRabbit <rabbit@yrabbit.cyou>

|/ | | | | | | | | | When a single primitive occupies several cells, care must be taken when manipulating the parameters of that primitive: when creating cells, each cell must receive a copy of all the parameters and not modify them unnecessarily. That is, if possible, it is better to make all parameter changes before dividing the primitive into cells. Signed-off-by: YRabbit <rabbit@yrabbit.cyou>

| * ice40: Add debugs to isBelLocationValid for SB_IOSean Anderson2022-12-071-4/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When there is a constraint conflict while placing IOs, the user gets an error message such as ERROR: Bel 'X0/Y27/io1' of type 'SB_IO' is not valid for cell 'my_pin' of type 'SB_IO' While this identifies the problematic cell, it does not explain why there is a problem. Add some verbose messages to allow users to determine where the problem is. This can result in something like Info: Net '$PACKER_VCC_NET' for cell 'my_pin' conflicts with net 'ce' for 'ce_pin' which provides something actionable.
