Table 35. OR3TP12 FPGA Side Interface Combinatorial Path Delay Signals
OR3TP12 Commercial: V
DD
= 3.0 V to 3.6 V, 0 °C < T
A
< 70 °C.
Note: The combinatorial path parameters are measured from the input to the output (both on the FPGA side), excluding the interbufs, which
traverse the ASIC/FPGA boundary. The ORCA Foundry static analysis tool, trace, accounts for clock skew and interbuf delays on
the clock and data paths.
Table 36. OR3TP12 Interbuf Delays
OR3TP12 Commercial: V
DD
= 3.0 V to 3.6 V, 0 °C < T
A
< 70 °C.
Note: The interbufs are buffers that interface between the FPGA and the ASIC.
