Synopsys Platform Architect Models are a library of pre-built architecture components (transaction-level/SystemC-oriented models) designed for early SoC/SiP architecture exploration within Synopsys Platform Architect. The model portfolio is described by the vendor as intended to support evaluation of performance, power, and cost trade-offs prior to RTL availability by assembling system models with lower development effort than building them from scratch.
The vendor describes example architectural components such as traffic generators, interconnects, memory subsystems, and embedded processors, and states that the models are integrated into Platform Architect and described as validated for use during early development phases.
