XC4000E/EX/XL Program Readback 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.
The following guidelines reect worst-case values over the recommended operating conditions.
Note 1:
Timing parameters apply to all speed grades.
Note 2:
If rdbk.TRIG is High prior to Finished, Finished will trigger the rst Readback.
