Timing analyzed (TRCE) reports "0 items analyzed" for the following TIMESPECs:
This report is expected for the defined TIMESPECs above.
Although these TIMESPECs have 0 paths analyzed, they are used to derive other TIMESPECs that cover the needed paths. Therefore, these TIMESPECs are still needed in the UCF constraint file.
For instance, TIMESPEC TS_pl4_src_clk0_TSClk_dcmo is derived from TIMESPEC TS_TSClk, and it covers the timing constraints for all the TSClk paths.
These timing analyzer messages can be safely ignored.
