VCDS Development

Objective

To drastically increase the SoC design productivity

Features

VCore based design methodology
- VCore reuse based high-level design methodology.
- A VCore is reusable functional component, whose architecture and external interface are configurable. It is a high-level abstraction of a functional specification at the system and architectural levels.
High-level design modeling methodology
- System level modeling using VCores and architecture exploration methodology.
VCore synthesis technology
- Synthesis of a VCore's internal description and the interface between VCores.
VCore platform technology
- VCore database technology for VCore development and reuse.
