SpiProg is a programmer for SPI (Serial Peripheral Interconnect) compatible EEPROMs used in many modern small electronic devices such as cellular phones. The package contains building instructions for a very simple parallel port adaptor and source code of the programming software. It has a small built-in command line driven hex editor and supports devices like Xicor X25640 and Atmel AT25080.
THUD is a register transfer level (RTL) simulation environment optimized for cycle- based designs. The design is expressed in TH, a Scheme-based hardware description language (HDL) that supports 1/0/x operators and hierarchical instantiation. THUD can be used as a library, in batch mode, or through one of its interactive interfaces.
