hi
in actel flow, i have to write my timing constraints as SDC, referencing to net objects. the synthesizer handles them correctly, but the P&R program says error in SDC. i belive the P&R should be also timing driven, not only the synthesis.
probably the objects and object names disappeared after synthesis.
how to maintain ALL object/net names after synthesis in actel flow?
the syn_keep is what i tried gave errors, and i have to specify it to every net.
the best would be if i could maintain the entity hierarchy and all portnames of all entities in all files with one action. i mean i dont want to set some synthesis directives to every port/net separately.
