206 Chapter 9—Menu Reference

NOTE: 1) You cannot set the device delay of a subcircuit device since its general

delay characteristics are determined by its internal circuit. If any subcircuit

devices are selected, they will be ignored for device delay purposes. You

can set the pin delay on subcircuit devices to modify the path delay through

a particular pin. Delays on the devices or pins inside a subcircuit device are

not affected by any settings on the parent device using this command.

2) The Parameters command relies on numeric information in a specific

format being present in the Delay.Dev or Delay.Pin attribute fields. Any

invalid information in these fields will be ignored and default values used

instead.

General Delay Box

For any collection of devices and pins with delay characteristics, the fol-

lowing box is displayed:

The controls in this box are summarized in the following table.

Devices When this button is enabled, the other controls display and

set the device delay characteristic of the devices currently

selected in the circuit. Items such as Clock or subcircuit

devices, which have no device delay characteristic, will be

skipped.

Pins When this button is enabled, the other controls display and

set the pin delay characteristic of the pins currently selected

in the circuit.

# of devices / pins This shows a count of the devices or pins that will be

affected by changes made in this box.
