Today we played with a few open source logic analyzer clients in preparation for an upcoming prototype. The best we found is SUMP, written in Java. There’s also compatible host software for several FPGA development boards, we found even more ports floating around the web.

SUMP has a SourceForge page, but it doesn’t look very active. Jack Gassett’s ButterFly Platform has a SUMP compile for Windows that doesn’t require you to install the complete Java framework. You’ll also need the rxtx Java library for your platform.

Do you know of any other clients or SUMP resources?
