New Features in v4.4  

 

- ISE 11.1 software support 

- Virtex-5 TXT support 

 

Bug Fixes in V4.4 

 

(Xilinx Answer 32023) Virtex-4 or Virtex-5 core might fail in hardware  

- Incorrect setting of DLL_FREQUENCY_MODE attribute of the DCM for Virtex-4 and Virtex-5. The DLL_FREQUENCY_MODE should be set to HIGH in the UCF file for Virtex-4 and Virtex-5 designs. 

- CR 491141 

 

General Information 

 

(Xilinx Answer 20430) What is the power consumption of SPI-4.2 Lite Core?  

(Xilinx Answer 20017) Which I/O Standards are supported for SPI-4.2 Core?  

Multiple Cores: If you are using multiple SPI-4.2 Cores in a single device, see the Multiple Core Instantiation section under the Special Design Consideration chapter of the SPI-4.2 Lite User Guide. It is important to generate multiple cores with unique component names for each instance regardless of core configuration. 

 

Known Issues in v4.4  

 

Constraints and Implementation Issues 

 

(Xilinx Answer 22009) When implementing an SPI-4.2 Lite design through NGDBuild, several "INFO" and "WARNING" messages appear 

(Xilinx Answer 21998) When implementing an SPI-4.2 Lite design through MAP, several "WARNING" messages appear  

(Xilinx Answer 21999) When implementing an SPI-4.2 Lite design through BitGen, several "WARNING" messages appear  

(Xilinx Answer 22011) There are missing example constraints in the UCF file  

(Xilinx Answer 19999) "ERROR:BitGen:169 - This design contains one or more evaluation cores for which bitstream generation is not supported" 

 

General Simulation Issues 

 

(Xilinx Answer 21319) TDat Error: Data mismatch error in timing simulation 

(Xilinx Answer 22001) Design example results in warnings for source segmenting packets  

(Xilinx Answer 21350) Demo testbench results in RDat Protocol violation warnings  

(Xilinx Answer 21322) Timing simulation errors: SETUP, HOLD, RECOVERY violations  

(Xilinx Answer 22026) Simulating SPI-4.2 Lite design results in "Error: /X_ODDR HOLD Low VIOLATION ON D1 WITH RESPECT TO C;" 

 

Hardware Issues 

 

(Xilinx Answer 20022) When fixed static alignment is used, it is necessary to determine the best IOBDELAY (ISERDES) value or the best DCM setting (PHASE SHIFT) to ensure that the target system contains the maximum system margin and performs across voltage, temperature, and process (multiple chips) variations.
