Edit Bus Dialog

To order the pins correctly within the bus select a pin and use the up/down arrows to change its position within the bus.

To add a new pin to a bus click the New... button under Pins in Bus. This will launch the Add pin(s) to bus dialog. Multiple pins can be added in a comma separated list, e.g. "1,2,3,4,5".

A pin can be removed from the bus by selecting it and then clicking the Delete... button under Pins in Bus.

The Disable Value of a bus is the value which must be set in order to put the device into a safe state, to prevent it from driving nets. This prevents the connection test from driving nets which are also being driven by this device. The value can either be Input, Low, or High. Input tells XJTAG that the device will always drive this bus, so the connection test should not attempt to drive it from other devices.

Test Coverage check boxes are for the user to indicate what test coverage the XJEase tests (usually contained in the additional code files for the device) confer on the bus. This test coverage can then be used in the calculation of the circuit test coverage totals.
