Set_input_delay misunderstanding

--- Quote Start ---

Hello:

set_input_delay -clock { RX_CLK _Virtual } -clock_fall -min -$uC_tCOmin [get_ports { RC_Data0 }]

thank you

min delay should be min tCO without minus

BTW I tried your experiment and got funny different results when swapping vir_clk with sys_clk without changing anything else!!!:

case1

create_clock -name vir_clk -period 2.706

set_input_delay -clock vir_clk -max 6 [get_ports data

[*]]

set_input_delay -clock vir_clk -min 5 [get_ports data

[*]]

case2

create_clock -name sys_clk -period 2.706 [get_ports {clk}]

set_input_delay -clock sys_clk -max 6 [get_ports data

[*]]

set_input_delay -clock sys_clk -min 5 [get_ports data

[*]]
