path name

Hi all,

I have just start for Place & Route, and I have a problem,

After CTS step and CTS_opt step, I see the name of path timing has changed, but number of paths not change. For example,

- After CTS, I have a path timing: MICRO/INSTR_DECODER/IR_reg[7]/q (v) triggered by leading edge of 'CLKM' ---> MICRO/ACCUMULATORS/ACC_B_reg[15]/d (^) checked with leading edge of 'CLKM'

- After CTS_opt, I don't see this path timing, I just have: TLATCH_BLOCK/TLATCH_9A/TLATCHCELL_0/TLOUT_reg/q (v) triggered by leading edge of 'CLKM' ---> MICRO/ACCUMULATORS/ACC_B_reg[15]/d (v) checked with leading edge of 'CLKM'.

I don't understand why, hope anyone can help me this problem ?

Thanks,
