* Switch to potentially-sparse net users arraygatecat2022-02-271-5/+6
| | | | | | | | This uses a new data structure for net.users that allows gaps, so removing a port from a net is no longer an O(n) operation on the number of users the net has. Signed-off-by: gatecat <gatecat@ds0.me>
* gowin: recognize partnumbers of GW1NZ-1YRabbit2022-02-241-1/+1
| | | | | | | | | | | The model should be recognized by the partnumber, --family is needed only if the same partnumbers belong to different models. This is done in order to automatically generate parameters for calling nextpnr from Gowin files without problems: there also only partnumber is used and only in some cases the model is specified with the -name parameter and GW1NZ-1 is not such a case.

* gowin: Add support for true differential outputYRabbit2022-02-232-0/+87
| | | | | | | | | The new primitive appears as an amalgamation of two existing OBUF primitives. Compatible with older versions of apicula, although, of course, using TLVDS_OBUF with old databases will not bring the desired result, but no crash. Signed-off-by: YRabbit <rabbit@yrabbit.cyou>

* gowin: add an option to manually specify familyIcenowy Zheng2022-02-061-6/+11
| | | | | | | | | | | In the vendor IDE, there's a device family named GW1N-9C (which seems to mean C revision of GW1N-9), in which the model numbers are all the same with GW1N-9. Add an option to nextpnr-gowin to allow manually specified family for this situation. Signed-off-by: Icenowy Zheng <icenowy@aosc.io>

| * gowin: Add GUI.YRabbit2022-01-298-17/+6528
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Items such as LUT, DFF, MUX, ALU, IOB are displayed; * Local wires, 1-2-4-8 wires are displayed; * The clock spines, taps and branches are displayed with some caveats. For now, you can not create a project in the GUI because of possible conflict with another PR (about GW1NR-9C support), but you can specify the board in the command line and load .JSON and .CST in the GUI. Although ALUs are displayed, but the CIN and COUT wires are not. This is still an unsolved problem. Signed-off-by: YRabbit <rabbit@yrabbit.cyou>
* | gowin: Add a DS location recognitionYRabbit2022-02-031-12/+18
|/ | | | | | | | | For differential signals it is necessary to set the position of two pins at once: P and N.

* | gowin: Add simplified IO cells processingYRabbit2021-12-204-4/+77
|/ | | | | | | | | | | | | | | Some models have I/O cells that are IOBUFs, and other types (IBUFs and OBUFs) are obtained by feeding 1 or 0 to the OEN input. This is done with general-purpose routing so it's best to do it here to avoid conflicts. For this purpose, in the new bases, these special cells are of type IOBS (IOB Simplified). The proposed changes are compatible with bases of previous versions of Apycula and do not require changing .CST constraint files. Signed-off-by: YRabbit <rabbit@yrabbit.cyou>
* archapi: Use arbitrary rather than actual placement in predictDelaygatecat2021-12-192-5/+6
| | | | | | | | | | | | This makes predictDelay be based on an arbitrary belpin pair rather than a arc of a net based on cell placement. This way 'what-if' decisions can be evaluated without actually changing placement; potentially useful for parallel placement. A new helper predictArcDelay behaves like the old predictDelay to minimise the impact on existing passes; only arches need be updated. Signed-off-by: gatecat <gatecat@ds0.me>

* gowin: Add partnumbers and packages to the chipdbYRabbit2021-11-043-6/+29
| | | | | | | | | | Instead of parsing the partnumber with a regular expression, a simple table is used. This is done because the structure of the partnumber changes as new features appear (e.g., ES instead of C6/I5) This commit does not yet disable the very first regular expression check.
