set_disable_timing

[Altera_Forum]

I have a combinational timing loop I want to get rid of in my timing path. When a generate a clock to clock report, this shows up in the report, 

"LOOP ; 17 ; LCCOMB_X16_Y58_N4 ; i_MPBLOCK_CUSTOM|u_mse2|u_dst_fsm|adr_reg_nxt~0|combout"   I try running this from a tcl script: "set_disable_timing -from i_MPBLOCK_CUSTOM|u_mse2|u_dst_fsm|adr_reg_nxt~0|combout *"   On the tcl console I see this: "Warning: Cannot find the specified edge."   What do I need to put in for arguments to get TimeQuest to accept the set_disable_timing command?

The set_disable_timing is only a "band-aid" until I figure out how to get rid of the loop in rtl.  

 Does anyone have any advice on how to analyze the loop? I see it in the timing report and can trace it in the netlist, but it is very large and I am having difficulty converting the synthesized names to rtl net names. Is there some way to match the "loop" that shows up in the timing report with the rtl?
