Answers Database V2.1i COREGEN, VIEWLOGIC: "ERROR: cleanUpSymbolFile: Could not read symbol file: <project_directory>\sym\<modulename>.1" Record #7143 Product Family: Software Product Line: Coregen Product Part: Coregen Product Version: 2.1 Problem Title: V2.1i COREGEN, VIEWLOGIC: "ERROR: cleanUpSymbolFile: Could not read symbol file: <project_directory>\sym\<modulename>.1" Problem Description: Urgency: hot General Description: The Viewlogic VHDL2SYM executable uses the .VHD produced by the CORE Generator to generate a Viewlogic symbol for the core. The following errors are issued when trying to generate any of the Basic Element modules for Virtex for a Viewlogic schematic design:.     ERROR: cleanUpSymbolFile: Could not read symbol file: F:\wvoproj\bsblx\sym\test1.1     ERROR: invokeLinkScript: Failure to clean up Viewlogic symbol file. The problem is that the entity declaration in the VHD file used by the VHDL2SYM Viewlogic interface executable for CORE Generator module symbol generation does not contain the user-specified module name for the VHDL entity. Because of this, the name of the symbol created is some internally defined name like "gate_bit_bus". The subsequent processing step requires the module symbol and issues the errors above when it is unable to find it. This problem is limited to the BaseBLOX modules contained in the CORE Generator Basic Elements folder such as the FD Latch, MUX Bit, etc. Solution 1: The workaround is as follows: 1. Edit the .vhx file in your project directory and change the      VHDL entity name in this file to your module name. 2. Rename the .vhx file to <your_modulename> .vhd. 3. Within your project directory,run the following command from the      DOS prompt to generate your Viewlogic symbol:         vhdl2sym.exe -o <libraryname> -c <corename> -s 20 End of Record #7143 - Last Modified: 08/16/99 17:16
