CHIPKIT：一个敏捷、可重用的开源框架，用于快速测试芯片开发
CHIPKIT: An agile, reusable open-source framework for rapid test chip development
摘要：
当前特定领域架构（DSA）的趋势导致人们对研究测试芯片重新产生兴趣，以展示新的专用硬件。磁带输出还提供了巨大的教学价值，从真正的动手接触到整个系统堆栈。然而，成功的流片需要来之不易的经验，设计过程是耗时的，充满了挑战。因此，定制芯片仍然是少数研究小组的专利，通常专注于电路设计研究。本文介绍了CHIPKIT框架。我们描述了一个可重用的SoC子系统，它提供了基本的IO，片上可编程主机，存储器和外设。这个子系统可以很容易地扩展新的IP块，以生成定制的测试芯片。我们还提出了一个敏捷的RTL开发流程，包括一个代码生成工具VGEN。最后，我们概述了在整个设计周期中进行全芯片验证的最佳实践。
英文摘要：
The current trend for domain-specific architectures (DSAs) has led to renewed interest in research test chips to demonstrate new specialized hardware. Tape-outs also offer huge pedagogical value garnered from real hands-on exposure to the whole system stack. However, successful tape-outs demand hard-earned experience, and the design process is time consuming and fraught with challenges. Therefore, custom chips have remained the preserve of a small number of research groups, typically focused on circuit design research. This paper describes the CHIPKIT framework. We describe a reusable SoC subsystem which provides basic IO, an on-chip programmable host, memory and peripherals. This subsystem can be readily extended with new IP blocks to generate custom test chips. We also present an agile RTL development flow, including a code generation tool calledVGEN. Finally, we outline best practices for full-chip validation across the entire design cycle.
