RE: [juno] timing report is different between tempus and innovus
Hi, Bokong
I think innovus is right. It should be MCP2.
set_multicycle_path 2 -end -setup -from [get_cell inst_master_delay/inst_mstr_dly_control/bypass_reg]
set_multicycle_path 1 -end -hold -from [get_cell inst_master_delay/inst_mstr_dly_control/bypass_reg]
I don’t know why tempus is wrong.
Thanks
Ying

Which one is the correct timing report ?
The detail timing reports are as following.
