Qemu driver#
Software engineers (using QEMU) can use GNU Debugger (GDB) to instrument both the kernel and the driver to step through the code using breakpoints. Hardware engineers (using Riviera-PRO) can set break points in the HDL, examine data flow, and even analyze the code coverage and paths that are exercised by the software application running in QEMU. The communication is automatically handled by this bridge, and there is no need for extra interaction from verification engineer side.

Automatic connection with QEMU Bridge processįigure 2: AXI Transactions in Riviera-PRO QEMU Bridgeĭeveloped by Aldec based on SystemC Transaction Level Modeling (TLM), it is transaction accurate bridge that allows full SoC co-simulation between the Programmable Logic (PL) system and Processing System (PS).Turn on built-in AXI transaction recorder.Instantiation in HDL part of the project.Distributed with pre-compiled libraries.The process of AXI injection into design includes: For more information about using transactions in Riviera-PRO, refer to documentation Riviera-PRO Transactions. The following BFMs are supported by the Aldec AXI BFM:Įach BFM enables users to turn on built-in AXI transaction recorder for logging AXI transactions into ASDB (Aldec Simulation Database) format. User test bench can test the BFMs via Verilog or System Verilog tasks API provided by Aldec. The BFMs are delivered as encrypted Verilog and System Verilog modules. The AXI Bus Functional Models (BFMs) developed by Aldec for RTL simulation of AXI-based designs is available in Riviera-PRO. The QEMU Bridge connects Riviera-PRO and QEMU, and converts SystemC TLM transactions to AXI and vice versa providing a fast interface for co-simulation.įigure 1: HW/SW Co-Simulation Environment with Riviera-PRO and QEMU System integration and co-simulation of HDL code with software applications/drivers executing in QEMU is now simplified with the addition of the Aldec QEMU Bridge. Finding the issues in the testbed is often too late and can cause project delays.Īldec provides a HW/SW co-simulation interface between Riviera-PRO™ and QEMU (open-source processor emulator). Common issues related to HW/SW integration continue to increase, and yet they are only typically found in the testbed with the SoC FPGA running.
