程序从Spartan-3a移植到Spartan-6上，在implenment时MAP时间花了3小时左右，本程序在Spartan-3a 上的时间仅仅20分钟全部结束，请教高手怎么解决？小弟万分感谢！
补充：
（1）编译工具用的是ise12.3
（2）程序中调用了几十个IP核，其中包括30多个dsp核，其他不一一列举
（3）Spartan-6比Spartan-3a多了这个约束：PIN "sys_ctl/DCM_image/clkout2_buf.O" CLOCK_DEDICATED_ROUTE = FALSE;
以下是其他高手解答：
The mapping time for Spartan6 is definitely much longer than Spartan3, since the logic resource capacity is much larger in Spartan6 than Spartan3.
What I suggest here is:
1. Get a new workstation to run. A better CPU will make the mapping time much shorter.
2. Use more stable release. e.g. please change to 12.4 from 12.3. It will be faster. or you may chose to use 13.2.
3. Actually I do not think there is much you can do for your design. Just do not pushing your timing to extremes :P
Good luck with your design
