Critical Issue
Description
Starting in version 7.1, the C2H Compiler does not support SOPC Builder systems created in SOPC Builder version 7.0 or earlier (systems based on a class.ptf file).
Resolution
Before using the C2H Compiler, you must upgrade your SOPC Builder system. Open the system in SOPC Builder version 7.1 or later. SOPC Builder prompts you to convert the system, creating a *_hw.tcl file compatible with the C2H Compiler.
