DEVICE SUPPORT 2.1. ISE The following device families are supported by the core for this release: All Series 7 devices All Virtex-6 devices All Spartan-6 devices 2.2. VIVADO The following device families are supported by the core for this release: All Series 7 devices 3. NEW FEATURE HISTORY 3.1 ISE v6.3 - Ongoing new device support. - Advanced Interleaved Channels (Configurable Bandwidth support) - Multi-column support for symmetric filter implementations - Re-introduction of Hilbert Transform, Single Rate Half-Band and Interpolated filters - C Model added 3.1 VIVADO v6.3 - Introduction to Vivado. - Same features as for ISE. 4. RESOLVED ISSUES 4.1 ISE - FIR Compiler v6.x - GUI may crash when Maximize_Dynamic_Range is selected - CR 627620 - FIR Compiler v6.x - Reload port allows boolean type in System Generator - CR 640607 - FIR Compiler v6.x - Custom column lengths ignored in System Generator for some core configurations - 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 - AR 41707 - CR 605099 - FIR Compiler v6.x : Event I/F mismatches between model and core - AR 42305 - CR 592301 - FIR Compiler v6.2 - Multi-Channel core data comes out on the wrong channel - The output shift channels when using a multi-channel, interpolate by 2, odd number of symetrical coefficients, with oversample rate of 3 with Block RAM selected for memory implementation - AR 42727 - CR 614460 - N/A 4.2 Vivado - 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. 5.2 Vivado 1. As per 1. above for ISE. 2. Core may fail to compile in XSIM. - CR667417 - AR50922 For a comprehensive listing of Known Issues for this core, please see the IP Release Notes Guide, www.xilinx.com/support/documentation/user_guides/xtp025.pdf 6.
