2026.01 January 2026

  • Added the inclusion of the PCIe C model to CoSim library compilation. These new libraries exits in PCIe/lib, with headers in PCIe/include
  • Changes in support of PCIe VC, including adding support for SetModelOptions and GetModelOptions
  • Added a VIrq co-simulation procedure, wrapped in a new CoSimIrq VHDL procedure, to raise interrupts independent of CoSimTrans where required
  • The rv32 RISC-V instruction set simulator library is updated to verion 1.3.1. New features include:
    • API access to internal cycle count
    • Registering of callback function on unimplemented instruction
    • Internal timing model configurable over API
    • Generation of software interrupt over external IRQ callback
    • Support for RV32B standard extensions (Zba, Zbb and Zbs)
    • Support for RV32_Zbc standard extension
    • Reading of binary program in addition to ELF support

2024.07 July 2024

  • Updated calls to CreateClock for it being moved to ClockResetPkg

2023.?? July 2023

  • Updates RISC-V ISS rv32 libraries and include headers for new features and fixes to support running FreeRTOS real-time operating system

2023.05 May 2023

  • Added split transaction methods for address bus model independent manager
  • Added support address bus model independent subordinate/responder
  • Added support for streaming bus model independent transactions
  • Added test data pattren generation methods
  • Added data check methods

2023.01 January 2023

  • New repository with ability to run C code in the testbench in a CoSim environment. See README.md
