4.1i FPGA Editor - The name filter tries to capitalize a search for "bufg*"

Description

Keywords: FPGA, Editor, cursor, full, time, length

Urgency: Standard

General Description:
If I have a BUFGMUX component named "bufg_sys_clk", and I try to find the component using "bufg*" in the name filter, the tools will not find my component. (When I enter "bufg*", the tools convert it to "BUFG*", which is not the component's name.)

If I search for "buf*", the tools will find the component.

Solution

The problem is that the filter combo is case-sensitive, but the filtering action is NOT case-sensitive.

When the you type the filter pattern and click "Return" in the list window, the application will check to see if a previously searched pattern in the combo list already exists. In this case, the "BUFG*" pattern was a previously defined pattern. As the search for a previous pattern is not case-sensitive, the conversion from "bufg*" to "BUFG*" occurs.

This problem is fixed in the latest 4.1i Service Pack, available at:

The first service pack containing the fix is 4.1i Service Pack 2.
