4.2isp1 XST - The GUI option for merging flip-flops into the IOBs does not appear to work as it did in the 4.1i software

描述

Keywords: XST, IOB, flip-flop, merge, duplicate, register, 4.1i

Urgency: Standard

General Description:
When I set the GUI option to merge the flip-flops into the IOBs for the XST tool, the registers to not seem to be pushed into the IOBs as they were in an older XST version. Additionally, the registers are not duplicated, even though the GUI option to duplicate registers is checked.

解决方案

This issue will be fixed in the 5.1i software, which is scheduled to be released in September, 2002.
