ASIC芯片全定制费用高、风险大、周期长,因此在全定制之前一般先用FPGA或CPLD等可编程逻辑器件做功能验证。但在一些空间极为有限、成本极低的应用场合,采用FPGA或者CPLD显然不是最佳的解决方案。而利用体积小、性能强、成本低的单片机实现芯片全定制将是一个不错的选择。按此设想,本文给出了一种基于微处理器的科学、经济、快速的ASIC芯片功能验证方案,并成功设计出用于某通信设备中的专用加密芯片。 ASIC chip full custom high cost, risk, long cycle, so before the full custom FPGA or CPLD generally used to do functional verification of programmable logic devices. However, in some applications where the space is extremely limited and the cost is very low, adopting FPGA or CPLD is obviously not the best solution. The use of small size, high performance, low cost microcontroller chip customization will be a good choice. According to this assumption, this paper presents a microprocessor-based scientific, economical and fast ASIC chip function verification scheme, and successfully designed for a communications device dedicated encryption chip.
