A logic analyzer project which aims to provide reliable, high speed (100MHz+), large capture depth, open-source gateware that can be used on a FPGA development board you already own, or as replacement gateware for commercial logic analysers that do not work with open-source tools such as sigrok.
This project aims to support FPGA boards with 10's MBs of capture memory (such as DDR3), which also have high-speed USB interfaces from which to download the captured data.
There are a number of other open-source logic analyzer projects, but these mostly focus on using limited internal FPGA memories (embedded block RAMs), and low-performance host interfaces (UART).

Compatible with Sigrok (via libsigrok), based on the following fork;
open-logic-bit also contains a built in test mode;
