全定制设计

半定制设计方法

半定制设计

方法又分成基于标准单元的设计方法和基于门阵列的设计方法。

基于门阵列的设计方法是在预先制定的具有晶体管阵列的基片或母

片上 通过掩膜互连的方法完成专用集成电路设计。半定制主要适合

于开发周期短，低开发成本 、投资、风险小的小批量数字电路设计。

该方法采用预先设计 好的称为标准单元的逻辑单元，如门电路、多

路开关、触发器、时钟发生器等，将它们按 照某种特定的规则排列

成阵列，做成半导体门阵列母片或基片，然后根据电路功能和要求

用掩膜版将所需的逻辑单元连接成所需的专用集成电路。

全定制设计周期最长，设计成本贵，设计费用最高，适合于批量很

大 或者对产品成本不计较的场合。

asic(application specific integrated circuit)

是专用集成电路。

目前，在集成电路界

asic

被认为是一种为专门目的而设计的 集成电

路。是指应特定用户要求和特定电子系统的需要而设计、制造的集

成电路。

asic

的特点是面向特定用户的需求，

asi c

在批量生产时与

通用集成电路相 比具有体积更小、功耗更低、可靠性提高、性能提

高、保密性增强、成本降低等优点。< /p>

asic-

定制

asic

有电路的设计，因此需 要大量人力物力，灵活性好但开发效率低下。

如果设计较为理想，全定制能够比半定制的

芯片运行速度更快。

半定制使 用库里的标准逻辑单元
