    4. RESOLVED ISSUES

      4.1 ISE

          - CR 630639

        - FIR Compiler v6.x - Latency information in the GUI doesn't match the core
          - AR 40200
          - CR 591161

        - FIR Compiler v6.x : Multi-column filters will not map/place
          - AR 40769
          - CR 594220

        - FIR Compiler v6.2 - The output for a Fractional Rate is in bursts rather than at regular intervals

            with oversample rate of 3 with Block RAM selected for memory implementation
          - AR 42727
          - CR 614460
          - N/A

    5. KNOWN ISSUES & LIMITATIONS

      The following are known issues for this core at time of release:

      5.1 ISE
        1. Unsupported v5.0 features - The following features are not supported by v6.3:
          - Distributed Arithmetic
          - Polyphase filter bank

        2. Memory collision errors - Netlist or UniSim structural model simulation may
            report Block RAM memory collision errors. These errors are issued by the Block RAM
            primitive when a write occurs and the read and write addresses match. However, a
            read or write event is qualified by read enable or write enable respectively.
            In operation, read and write events never occur to the same address at the same
            time so functionality is not affected by these apparent collisions.

      For a comprehensive listing of Known Issues for this core, please see the IP
      Release Notes Guide,
