Keywords: endpoint, high, speed, high-speed, PHY, logical, design environment, SRIO, RIO, rapid, IO, MGT, 11.1, I/O, Generator, physical, logicalio, transport, buffer, mgt

A Serial RapidIO v5.2 or v5.3 Core generated for the Virtex-4 FXT, with x4 lanes and 3.125G line rate might fail to meet timing on the following constraints:

TS_CLK0_BUF = PERIOD TIMEGRP "CLK0_BUF".4 ns HIGH 50% INPUT_JITTER 0.1 ns PRIORITY 0

TS_UCLK = PERIOD TIMEGRP "UCLK" 6.4 ns HIGH 50% INPUT_JITTER 0.1 ns PRIORITY 0

Solution

This is scheduled to be corrected in the SRIO v5.4 core (for release with ISE 11.3).
