XC9500 CoolRunner-II/XPLA3 CPLDs - What are the "Hitop" and "Hprep6" programs?

Description

Keywords: 9500, CPLDFit, command, flow, implementation, step

Urgency: Standard

General Description:
When implementing a Xilinx CPLD, the programs "Hitop", "CPLDFit", and "Hprep6" are invoked. What is the function of these programs?

Solution

The "Hitop" program fits designs into the XC9500 CPLDs in the 4.1i and earlier versions of Xilinx software. Hitop has been replaced with "CPLDFit" in 5.1i and later versions. The "Hprep6" program generates a programming (e.g., JEDEC) file for CPLD devices. You can invoke all programs from the command line.
