VaST Modeling

Peripheral Device Builder Creates Powerful Virtual Models

Peripheral Device Builder (PDB) is one of VaST's "constructor" class of tools that allows users to quickly create their own virtual models. PDB automates much of the peripheral modeling task and then allows users to rapidly integrate the models directly into a platform.

Peripheral Device Builder models interrupt controllers, DMA controllers, UARTs, IO devices, timers, and many others. PDB not only automates much of the model coding process but also provides a common code base thus helping to ensure consistency and quality by removing human error.

VPM Transformer

In addition to VaST creating virtual models of processors, VaST customers can now use VPM Transformer (VPM-T), a toolset and methodology for modification of the instruction set and timing of a VaST Seed VPM. The VaST Seed VPM models the instruction set, micro-architecture, pipelining and other behavior of a specific microprocessor. Users then generate a new VPM in the same microprocessor family by adding, removing or replacing instructions in the VaST Seed VPM instruction set. The behavior, timing and mnemonic aspects of an instruction can be changed independently.
