LogiCORE SPI-4.2 (POS-PHY Level 4) v6.0 - SnkFFPayloadDIP4 is not asserted for a 2-byte packet

描述

General Description 

When I use an SPI-4.2 v6.0 core, SnkFFPayloadDIP4 fails to assert when the packet size is less than 2 bytes. 

 

Example scenario:  

 

RDat: <0070>< 80e3><0000><f01e><0073>  

RCtl: ....<0>........<1>........<0>......<1>.......<0>..  

 

Both control words above have DIP4 errors.  

 

In this case: 

- SnkFFDIP4Err asserts properly for both control words.  

- SnkFFPayloadDIP4 does not assert for the second control word.  

- Additionally, the SnkFFBurstErr signal does not assert in this case.

解决方案

This issue will be addressed in the SPI-4.2 v6.1 release.
