After I synthesized in design compiler, I write_milkyway to store my design.
Then I read_milkyway in Primetime, after read milkyway, when I report_timing, I should get the timing report show all the pints in critical path are annotated, but I didn't get it, all the points don't have * to show they are annotated, I don't know why...
In prime time, I used to set_annotated_delay to annotate some cells rise delay, but I only can annotate delay belong to IVX4, BFX4,BFX9.... all the others cell like NAND2X3, NOR2X2,NAND3X5... all of them cannot be annotated!
I got the warning: The timing arc (0->1,0->Z,Z->1)of cell 'u3_control/U57' from 'B' to 'Z' could not be annotated.(SDF-019)
Error: No timing arc in cell 'u3_control/U57(HS45_LS_NOR3X2)' from pin 'B' to 'Z'.(PTE-008)
....
...
all of the cell from nand, nor,and or has same problem, but inv don't have this problem. I don't why..
And in SDF file, I can find all the timing information of them, but primetime has error..
Anybody can bring some idea of the potential mistake?
