Xilinx Vivado 2020.2 represents a key transition point in FPGA design history, primarily known for being the first version to fully integrate Vitis HLS as the default high-level synthesis tool. This release focuses on stability for UltraScale+ devices and enhanced support for the Versal architecture. Key Technical Improvements & Bug Fixes

  1. Critical Bug Fixes: Several critical bugs have been fixed, ensuring improved stability and reliability of the software.
  2. Timing Analysis and Constraints: Issues related to timing analysis and constraints have been resolved, providing more accurate results and reducing design implementation time.
  3. Simulation and Debug: Bugs affecting simulation and debug have been fixed, enabling designers to more efficiently identify and resolve design issues.
  4. Design Implementation and Optimization: Fixes have been made to improve design implementation and optimization, allowing for better performance and reduced power consumption.

While 2020.1 felt like a beta test for Versal support, 2020.2 functions as a mature point release. The fixes to incremental compile, XSIM, and AXI SmartConnect remove the three biggest obstacles to daily productivity. xilinx vivado 20202 fixed

  • Run incremental steps: Run synthesis only (synth_design) then address issues before running implementation.
    • sudo apt install libncurses5 libtinfo5 libc6-dev-i386 lib32z1

    Step 3: The "Tcl Script Breaks on source" Fix

    Issue: In 2020.1, source -notrace would sometimes fail silently. In 2020.2, this is fixed, but a new issue emerged: namespace import fails if not preceded by a package require. Fix: Add package require qsys (or relevant package) before any namespace import ::tcl::mathop::* lines. Xilinx Vivado 2020
