Keyword: Spartan-XL, Synplicity, clock, infer, global, buffer
General Description:
Synplify limits global buffer insertion to four. However, in some architecture (such as Spartan-XL), a design can use up to eight BUFGLS. How do I change BUFG limit from 4 to 8 for these architectures?
Set the following attribute in the .sdc file to increase the limit of BUFG insertion in Synplify:
define_global_attribute xc_global buffers (8)
