| * | gowin: add PLL pins processingYRabbit2022-12-045-10/+133
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 GW1N-1 and GW1NZ-1 have a similar PLL, but the board with the former chip is already very hard to buy, so let's experiment with a more affordable chip. Signed-off-by: YRabbit <rabbit@yrabbit.cyou>

| * gowin: add initial PLL supportYRabbit2022-11-106-1/+227
| | | | | | | | | | | | | | | | | | | | | | 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>
