|/ | | | | | | | | | | | | | | | | | In the Gowin chips, the tiles are connected to each other by a one-hop wire, among others. There are 4 one-hop wires, of which 2 are shared between north/south and east/west, have three names: e.g. SN10 and N110 and S110. But only one of them, the first, occurs as a sink for PIP, that is, you can not get a route that would pass through the S110 for example. This commit corrects the names to SN?0 and EW?0 at the wire creation stage to avoid dead wires. In addition, the SN?0 and EW?0 are among the few sinks for global clock wires and now there is the possibility of a more optimal clock routing. Signed-off-by: YRabbit <rabbit@yrabbit.cyou>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Gowin chips have a highly sophisticated system of long wires that are wired to each cell and allow the clock or logic to spread quickly. This commit implements some of the capabilities of the long wire system for quadrants, leaving out the fine-tuning of them for each column. To make use of the long wire system, the specified wire is cut at the driver and a special cell is placed between the driver and the rest of the wire. * VCC and GND can not use long wires because they are in every cell and there is no point in using a net * Long wire numbers can be specified manually or assigned automatically. * The route from the driver to the port of the new cell can be quite long, this will have to be solved somehow. * It might make sense to add a mechanism for automatically finding candidates for long wires.
