13.1 EDK - How can I pass XST switches?
描述
Is there a way to pass XST switches and constraints in EDK?
解决方案
You can pass XST options by creating XCF files for your instantiated cores. Then, put the XCF files into the <proj>/etc/ directory. For example, most instantiated cores have a wrapper HDL file as it's the top level file. This would then need an XCF file as <instance>.xcf (no wrapper in the XCF name) in the <proj>/etc/ directory.
For more information on XST Constraint Files (XCF), refer to the XST User Guide.
