Description

This Answer Record describes how to migrate from v1.2 to v2.0 of the SPI-4.2 Lite Core. It also describes the signal changes made to the core. While every attempt was made to keep constraints and input and output signals as consistent as possible between versions, certain modifications are required to upgrade from v1.2 to v2.0. The following sections are included in this Answer Record: 

 

- Core Signal Changes 

- Wrapper File Changes 

- NCF File Changes 

- UCF File Changes 

- UCF Migration Steps

Solution

Core Signal Changes  

 

NOTE: The following signals were added in the v2.0 Core: 

 

SnkFFPayloadDIP4 (Output) - new in v2.0  

Please see the data sheet for more information. If not needed, leave unconnected.  

 

SnkFFBurstErr (Output) - new in v2.0  

Please see the data sheet for more information. If not needed, leave unconnected.  

 

RDClk_DCMLost (Output) - new in v2.0  

Output signal to indicate that RDClk has stopped toggling. Please see the data sheet for more information. In not needed, leave unconnected.  

 

SnkBusErrStat[7:0] (Output) - new in v2.0 

Output bus to indicate which type of SnkBusErr has occurred. Please see the data sheet for more information. If not needed, leave unconnected. 

 

SnkDIP2ErrRequest (Input) - new in v2.0 

When asserted high, it causes the Sink status logic to invert the calculated DIP2 values and send out incorrect DIP2's on the RStat bus for system diagnostics. Please see the data sheet for more information. If not needed, tie it to logic level "0". 

 

Wrapper File Changes 

 

The v2.0 wrapper file replaces the v1.2 wrapper file, or manually add the signal changes mentioned above. 

 

NCF File Changes 

 

The v2.0 NCF files replace the v1.2 NCF files. 

 

UCF File Changes 

 

The v2.0 UCF file replaces the v1.2 UCF file.
