XC4000E Boundary Scan (JTAG) Switching Characteristic Guidelines
Testing of the switching parameters is modeled after testing methods specied by MIL-M-38510/605. All devices are 100%
functionally tested. Internal timing parameters are not measured directly. They are derived from benchmark timing patterns
that are taken at device introduction, prior to any process improvements. For more detailed, more precise, and more
up-to-date information, use the values provided by the XACT timing calculator and used in the simulator. These values can
be printed in tabular format by running LCA2XNF -S.
The following guidelines reect worst-case values over the recommended operating conditions. They are expressed in units
of nanoseconds and apply to all XC4000E devices unless otherwise noted.

Note 1:
Input setup and hold times and clock-to-pad times are specied with respect to external signal pins.
Note 2:
Output timing is measured at pin threshold, with 50pF external capacitive loads (incl. test xture). Slew-rate limited output
rise/fall times are approximately two times longer than fast output rise/fall times. For the effect of capacitive loads on ground
bounce, see the “Additional XC4000 Data” section of the Programmable Logic Data Book.
Note 3:
Voltage levels of unused pads, bonded or unbonded, must be valid logic levels. Each can be congured with the internal
pull-up (default) or pull-down resistor, or congured as a driven output, or can be driven from an external source.
