  • External Memory Interfaces Intel® Stratix® 10 FPGA IP
  • Memory Interfaces and Controllers
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to a problem in the Intel® Quartus® Prime Pro Edition software version 21.1 for Linux* or Windows* operating systems,  you may see an error message similar to the following when generating the EMIF or PHYLite IP for the Intel Stratix® 10 or the Intel Agilex™ devices:

    Error: no such variable       

        (read trace on "::env(IP_ROOTDIR)")       

        invoked from within    

        "return "$::env(IP_ROOTDIR)/altera/emif/ip_arch_nd/fw_src""

        invoked from within"get_iossm_firmware_source_dir 1"       

        (procedure "get_sim_cal_code_hex_src_filename" line 2)

        (procedure "_generate_common_fileset" line 36)       invoked from within

    Resolution

    To work around this problem, ensure the Linux* or Windows* environment variable "IP_ROOTDIR" is set to the ip sub-directory in the Intel Quartus Prime Pro Edition software installation. 

    An example for the Windows* version is: IP_ROOTDIR = C:\intelFPGApro\21.1\ip

     

    This problem is fixed starting with the Intel® Quartus® Prime Pro Edition software version 21.2.
