Using Multiple Transaction Nodes in OSVVM Co-simulation

Simon June 13, 2023 CoSim, Model Independent Transactions, New Features, Transaction Based Testbench 0

Introduction The OSVVM co-simulation environment has the ability to generate transactions from C++ to drive various virtual components (VCs), such as AxiBus, AxiStream, Ethernet, Uart, dual port RAM etc. But did you know that you can drive multiple VCs from within the same test bench, all driven by C++ software? To do this we have the concept of ‘nodes’. The OSVVM co-simulation documentation does ... »

Modelling Interrupts with OSVVM Co-simulation

Simon April 17, 2023 CoSim, Model Independent Transactions, New Features 0

Introduction In this article I want to give some thoughts on how to model interrupts within the OSVVM co-simulation environment. The manual details how to register an interrupt callback function with the software and this is called whenever the interrupt request input (IntReq) to the CoSimTrans VHDL procedure changes with the new state. This makes the interrupt request state available to the softw... »
