| | | | | | | | | Add new definition for parse_lattice_param Now parse_lattice_param is design to parse Property rather than search for it in cell. This functionalty was move to parse_lattice_param_from_cell. Signed-off-by: Maciej Dudek <mdudek@antmicro.com>

* Switch to potentially-sparse net users arraygatecat2022-02-272-24/+27
| | | | | | | | 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>

* nexus: reduce OSCA worst case to 7%Dan Callaghan2022-02-101-1/+1
| | | | | | | | | | | The current version of Crosslink-NX Family Data Sheet lists the high frequency oscillator maximum frequency as 481.5MHz (that is, 7% higher than its nominal 450MHz): https://www.latticesemi.com/-/media/LatticeSemi/Documents/DataSheets/CrossLink/FPGA-DS-02049-1-2-1-CrossLink-NX-Family.ashx?document_id=52780 Older documents listed a wider frequency range but ±7% is the range for production parts.

* archapi: Use arbitrary rather than actual placement in predictDelaygatecat2021-12-192-8/+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>
