Troubleshooting a transaction-leve model

摘要

The goal of OSCI (Open SystemC Initiative) TLM (transaction-level modeling) 2.0 is to enable high-level component models to simply plug into and play with each other in a system model. The standard identifies modeling styles, several interfaces, a generic payload, and more than 150 rules to define the expected behavior in the simulation. For the system model to work correctly, designers must comply with the standard. Finding errors in compliance can be a major problem, however. Nevertheless, approaches exist for troubleshooting system models to find noncompliant areas.rnTLM 2.0's 150 rules specify the expected behavior of a transaction and restrictions to avoid system malfunctions. The OSCI TLM working group defined TLM 2.0 specifications with respect to initiator and target pairs. A typical design has several initiators and targets, which connect through interconnects (Figure 1). The interconnect serves as both a target and an initiator.
