celebrating fall with fletcher's checksum

This post originally appeared on my website.

why are checksums useful for fpga development?

Checksum functions are useful for error detection and data integrity. With respect to FPGA architecture development, a checksum can ensure the system is able to retain its state. For example, an FPGA programmed to behave like an AND gate should not start to act like an OR gate due fluctuations in voltage or temperature. Such problems may be caught by computing the checksum of the bitstream before configuring the FPGA, operating the device in the lab, and then extracting the bitstream and re-computing the checksum to ensure it has not changed.

The last two FPGAs that I worked on-with Indiana University's SAIL-IN Lab and the QuickLogic Corporation-used a scan chain configuration interface which lent itself well to bitstream verification via checksum. The scan chain acts like a serial shift register, stringing together all the configuration chain flip-flops in the FPGA fabric. As the bitstream flows through the head of the scan chain, one bit at a time, its checksum may be computed; and later re-computed as it flows out of the tail. For context, imagine a small, thirty-two flop scan chain and the corresponding bitstream, 0xdeadbeef. On the way in, the Fletcher's (32-bit) checksum will be 0xf13b. If the post-configuration checksum does not match, the engineers would know that there is an issue with the FPGA architecture.

Fletcher's checksum also produces check bytes (or a "tag"), which can be appended to the end of the original data, such that the new checksum of the data and the check bytes is zero. For the example bitstream 0xdeadbeef, the resulting check bytes are 0xd2f1. And the checksum of 0xdeadbeefd2f1 is 0x0.

fletcher's checksum in systemverilog

Based mostly on the Wikipedia entry for Fletcher's checksum, I produced a parameterized, three-state module which computes the checksum and check bytes of a data stream. The SystemVerilog closesly follows the below psuedo-code. For the Fletcher-32 checksum, data arrives as 16-bit half-words.

Eventually, I'd like to wrap it in a SPI interface and submit it to TinyTapeout, but for now here's the bare RTL. The most up-to-date code is also available on GitHub:
