**Obsolete Solution**: XC7300 : How to force a wired-AND function into the UIM in Xabel-CPLD
Record #1190
Product Family: Software Urgency: Standard General Description: The UIM (Universal Interconnect Matrix) in the XC7300 is capable of performing wired-AND functions. The software will automatically use this capability when possible to improve resource utilization. However, it is possible to manually specify a function to be implemented in the UIM, by using the NODE (UIM) statement in the ABEL file. Solution 1: To force the CPLD fitter to implement the function in the UIM, use the following XEPLD Property statement in the Declarations section of the ABEL code: XEPLD Property 'NODE (UIM) signal_name'; For example: MODULE FORCE_UIM Q0, Q1, Q2, Q3 pin; TCO pin; XEPLD Property 'NODE (UIM) TCO'; EQUATIONS TCO = Q0 * Q1 * Q2 * Q3; END End of Record #1190 - Last Modified: 07/30/99 17:55 |
