3.3 User System Interface Circuit
3.3.1 User System Interface Circuit
The circuits that interface the evaluation chip in the emulator to the user system include buffers and resistors.
When connecting the emulator to a user system, adjust the user system hardware compensating for FANIN,
FANOUT, and propagation delays.
The AC timing values when using the emulator are shown in table 3.2.
Note: The values with the emulator connected, in table 3.2, are measurements for reference and are not
guaranteed values.
