Designing with the XC5200 family using synthesisRecord #1017
Product Family: Hardware * Clock enables : Each CLB shares a dedicated clock enable. The more clock enables you have, the harder it is for the placer to put things in the same CLB. This spreads the logic out, causing more nets and routing delays. * Asynch resets : Same story as above. * Horizontal LL : The more TBUFs you use, the more you restrict the router. It's harder for the router to get across the chip. End of Record #1017 - Last Modified: 05/20/96 15:27 |
