11.4 System Generator for DSP - Why does an error occur when I am trying to import a Chipscope data?

Description

I followed the instructions in System Generator for DSP User Guide to import data from Chipscope analyzer using the 'xlLoadChipScopeData' command, but I encountered the following errors:

xlLoadChipScopeData('csp_export_003.prn')
??? Error using ==> xlLoadChipScopeData at 61
Error converting the value 1FF to a double precision number.
Only signed and unsigned decimal numbers are supported


Solution

Currently, Matlab only accepts Chipscope database when the radix is decimal.

To fix this error, go to the SIGNALS panel (bottom left) of Chipscope Inserter and right-click on your buses. From there you can set the radix to Decimal.

This is a known limitation which will be addressed in a future release.
