* BUGFIX: disable the thousands separatorYRabbit2022-03-161-1/+8
| | | | | | | The wire numbers are very large and it is undesirable to use a thousand separator there. This is a side effect of enabling locale. Signed-off-by: YRabbit <rabbit@yrabbit.cyou>

* Switch to potentially-sparse net users arraygatecat2022-02-2714-260/+285
| | | | | | | | 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: Add GUI.YRabbit2022-01-292-0/+4
| | | | | | | | | | | | | | | * 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>

* generic: Refactor for faster performancegatecat2021-12-301-9/+8
| | | | | | | | This won't affect Python-built arches significantly; but will be useful for the future 'viaduct' functionality where generic routing graphs can be built on the C++ side; too. Signed-off-by: gatecat <gatecat@ds0.me>
* archapi: Use arbitrary rather than actual placement in predictDelaygatecat2021-12-198-11/+34
| | | | | | | | | | | | 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>

| * Fix chain swapMaciej Dudek2021-09-231-2/+15
| | | | | | | | | | | | | | | | | | | | | | | | Issue was due to dest_bels being not cleared between clusters unbindes, causing newly bind bels to be unbinded and having their old bel value changed to new bel value. Then when swap failed 2 cells were being bind to a single bel. I tested leaving dest_bels in the function scope and moving it to the loop scope. Code with dest_bels in the loop scope was faster than leaving it in the function scope, and checking if the cell is in the processed cluster. Signed-off-by: Maciej Dudek <mdudek@antmicro.com>
