timequest warning

1,020 Views

I build a nios cpu in my project. The SOPC generate a file named "cpu.sdc ". In this file there is a statement : "set_false_path -from [get_keepers *$cpu_oci_debug_path|monitor_ready] -to [get_keepers *$cpu_jtag_tck_path|monitor_ready_sync1]".

When I use Timequest Timing Analyzer , there's waring message : "*cpu:the_cpu|cpu_nios2_oci:the_cpu_nios2_oci|cpu_jtag_debug_module_wrapper:the_cpu_jtag_debug_module_wrapper|cpu_jtag_debug_module_tck:the_cpu_jtag_debug_module_tck|monitor_ready_sync1 could not be matched with a keeper."

How can I do to resolve this message waring?
