Specific Delays Excluding Logic
You can create subgroups based on names with “EXCEPT”
Example:
Assume this design has several data busses that all start with “DATA”. Use the EXCEPT command to create a group with all the pads except the data pads.
-
- TIMEGROUP CTRL_PADS = PADS: EXCEPT (DATA*);
- TIMEGROUP DATAPINS = PADS(DATA*);
- TIMESPEC TS_IO1=FROM:CTRL_PADS:TO:FFS:20;
- TIMESPEC TS_IO2=FROM:FFS:TO:CTRL_PADS:20;
- TIMESPEC TS_IO3=FROM:CTRL_PADS:TO:CTRL_PADS:30;
- TIMESPEC TS_IODATA=FROM:DATAPINS:TO:FFS:15;
