timer_set_maxdelay

Adds a maximum delay constraint to the specified path.

timer_set_maxdelay -from source_pin \

-to destination_pin \

[-unit {value}] -delay delay_value

Arguments

-from source_pin

Specifies the name of the source pin in the path.

-to destination_pin

Specifies the name of the destination pin in the path.

-unit {value}

Specifies whether the delay unit is in nanoseconds or picoseconds. The following table shows the acceptable values for this argument:

Value	Description
ns	Sets the delay in nanoseconds
ps	Sets the delay in picoseconds

-delay delay_value

Specifies the actual delay value for the path.

All

For the ProASIC3/E, ProASICPLUS, ProASIC, Axcelerator, SX-S, SX-A, and eX families, Actel recommends that you use the equivalent SDC command set_max_delay.

The following example sets a maximum delay of 20 nanoseconds from register reg1 to output pin out1:

timer_set_maxdelay -from {reg1:CLK} -to {out1} -unit {ns} -delay 20.00
