説明

General Description 

Timing analyzed (TRCE) reports "0 items analyzed" for the following TIMESPECs:  

TS_RDCLK_P  

TS_SysClk_P  

TS_TSClk  

TS_stat_syn_ver_pl4_snk_top0_U0_clk0_RDClk0_dcmo

ソリューション

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.
