|/ | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Uses the information of the special input pins for the PLL in the current chip. If such pins are involved, no routing is performed and information about the use of implicit wires is passed to the packer. The RESET and RESET_P inputs are now also disabled if they are connected to VSS/VCC. Signed-off-by: YRabbit <rabbit@yrabbit.cyou>

| | | | | | | | | | | | | | | | | | | | | | The rPLL primitive for the simplest chip (GW1N-1) in the family is processed. All parameters of the primitive are passed on to gowin_pack, and general-purpose wires are used for routing outputs of the primitive. Compatible with older versions of apicula, but in this case will refuse to place the new primitive. Signed-off-by: YRabbit <rabbit@yrabbit.cyou>
