AR# 58745

描述

Early expiry of the Simplex timer in the Simplex-TX core results in no CHANNEL_UP assertion in the Simplex-RX core.

This is observed in Artix-7 GTP and Virtex-7 GTH based cores.

解决方案

Increase the simplex timer (simplex_timer_r) from 16-bit to 18-bit and increase the other timeout values given below:

• aligned_timer = 158990
• bonded_timer = 162996
• verify_timer = 163508

These changes must be applied in <component name>_core.v[hd] of the Simplex-TX IP.

This issue will be fixed in the next VIVADO release (v10.2) of the core.
