Virtex-II Pro RocketIO - When is RXCHECKINGCRC asserted after receiving the EOF?

描述

When is RXCHECKINGCRC asserted after the EOF is received?

解决方案

Regardless of RXDATAWIDTH, the latency is 4-5 RXUSRCLK cycles.  

 

This is not exact, as a clock domain crosses from RXRECCLK to RXUSRCLK; although it is always exact in simulation, there is a possibility of phase offset between RXRECCLK and RXUSRCLK.
