摘要

本文从控制数据流程图规范出发,考虑了寄存器-传输的综合和优化。与资源约束下的调度相比,我们推导了一个没有对资源施加约束的寄存器-传输(RT)描述。最初的rt级描述可能看起来有过多的功能单元和多路复用器,但它通常也会表现出高信号再收敛。我们用非平凡的基准示例证明,高信号再收敛的区域也在rt级提供了高的再合成和优化潜力,产生了在布局面积、路径延迟和门级可测试性等各个方面与替代方法具有可比性和竞争性的标准单元实现。只有在优化初始描述后,才能在rt水平上检查资源分配的权衡。我们生成的rt级描述作为OASIS的顶级输入,OASIS将其扩展到所需的数据路径组件,综合所有控制规范,通过去除冗余执行测试生成和全局优化,并提交最终的标准单元网络列表,用于自动放置和路由。

Bridging Behavioral and Register-Transfer Synthesis
This paper considers register-transfer synthesis and optimization from a control-data flowgraph specification. In contrast to scheduling under resource constraints, we derive a register-transfer (RT) description without imposing constraints on resources. The initial RT-level description may seem to have an excessive number of functional units and multiplexors, however it will typically exhibit also high signal reconvergence. We demonstrate with non-trivial benchmark examples that regions of high signal reconvergence offer high resynthesis and optimization potential also at RT-level, producing standard cell realizations that are comparable and competitive with alternate approaches in all aspects: layout area, path delay and gate-level testability. Tradeoffs in resource allocation are examined at RT-level only after optimizing the initial description. The RT-level description we generate serves as a top-level input to OASIS, which expands it to the required data-path components, synthesizes all control specifications, performs test generation and global optimization by redundancy removal and submits the final standard cell netlist for automatic placement and routing.
