The Add Read Controls command defines the circuit read control lines and assigns their off-state values.

You can use clocks, constrained pins, or equivalent pins as read control lines if their off-states are the same.

Arguments

∙0

A literal specifying that 0 is the off-state value for the read control lines.

∙1

A literal specifying that 1 is the off-state value for the read control lines.

∙primary_input_pin

A required repeatable string that specifies the primary input pins you designate as read control lines and to which you are assigning the given off-state value.

Examples

The following example assigns an off-state value of 0 to two read control lines, r1 and r2:

add read controls 0 r1 r2 set system mode atpg add faults -all
