HDL代码风格对综合的影响深人探讨

目前综合器的优化功能越来越强，大部分设计都可以被优化。设计工程师也越来越依赖于综合工具，然而综合器的优化结果主要还是依靠设计工程师的代码风格。设计风格对综合结果的影响可以用一句话概括：“好的代码设计风格会使综合器事半功倍，达到最优的综合结果；不好的代码设计风格会使综合器南辕北辙，产生错误的综合结果。”有时候问题都源于其代码风格不尽合理，而并不在于综合器。

The Impact of Comprehensive on HDL Coding Style

Nowadays the synthesis tools is becoming more and more powerful,most of the design can be optimized.And the engineers rely more and more on the tools,however the result of the synthesis most due to the coding style.A speech that can summaries the impact of the coding style on the synthesis result is：good coding style can get twice the result with half the effort and get a good synthesis result;on the other hand bad coding style get half the result with twice the effort and may get a wrong synthesis result.Sometimes problems result in bad coding style but not synthesis tools.
