report_delay_calculation problem with 2-input nand gate

[ajhunt18]

What will be the command if I am to calculate the delay of a 2-input nand gate? what should I put in the "-from" portion?

please help.

you must do 2 report. because RDC command just report delay from a startpoint to a endpoint.

Okay. Thanks! But should I add the cell delays given by the 2 RDC reports?

example: you have NAND cell with 2inputs A/B and output Z. you should:
RDC -from A -to Z
RDC -from B -to Z
when I verify a library. I do:
foreach INPUTs [list of all inputs] {
foreach OUTPUTs [list of all outputs] {
RDC -from $INPUTs -to $OUTPUTs > report.$INPUTs.to.$OUTPUTs.rpt
}
}
