10.1 EDK - ERROR:MDT - rgb2gray_sm () - couldn't open "../../../pcores/ rgb2gray_sm_v1_00_a/doc/html/api/index.template"


This is an issue confined to pcores exported from SysGen. The design works in XPS. However, when the software application is imported in SDK, libgen generates the following error:

ERROR:MDT - rgb2gray_sm () - couldn't open

"../../../pcores/rgb2gray_sm_v1_00_a/doc/html/api/index.template": no such

file or directory

while executing

"open $fn r"

This issue arises because of the difference in the path where libgen is executed from in XPS and SDK.

The working directory in SDK is:


whereas in XPS it is:


and hence the errors in SDK.

The resolution is to change the path in the ".tcl" file generated along with the pcore. You have to replace the line

expand_Template_File "../../../pcores/${ipname}_v${ipver}/doc/html/api/index.template" "../../../pcores/${ipname} _v${ipver}/doc/html/api/index.html" $hw_inst $ws $rs $ipname 1


expand_Template_File "../../../../../pcores/${ipname}_v${ipver}/doc/html/api/index.template" "../../../../../pcores/${ipname}_v${ipver}/doc/html/api/index.html" $hw_inst $ws $rs $ipname 1
