Catherine	77187613e3	kernel: look up ports when applying clock constraints. (#1448 ) prjunnamed does not emit a net alias for toplevel ports. This works fine for constraining IOs but breaks clock constraints. This commit expands clock constraint application code to look up net aliases first, ports second.	2025-01-31 08:30:39 +00:00

gatecat	09e388f453	netlist: Add PseudoCell API When implementing concepts such as partition pins or deliberately split nets, there's a need for something that looks like a cell (starts/ends routing with pins on nets, has timing data) but isn't mapped to a fixed bel in the architecture, but instead can have pin mappings defined at runtime. The PseudoCell allows this by providing an alternate, virtual-function based API for such cells. When a cell has `pseudo_cell` used, instead of calling functions such as getBelPinWire, getBelLocation or getCellDelay in the Arch API; such data is provided by the cell itself, fully flexible at runtime regardless of arch, via methods on the PseudoCell implementation.	2022-07-08 14:30:57 +02:00
