This package provides the ability to interpret some communication messages contained in VCD (Value Change Dump) files. There are three components: cmu_vcd.py processess VCD files and delivers value change notifications to subscribed observers. This wraps ANTLR-generated parser code: * ValueChangeDump.g -- A near-complete VCD grammar; produces an AST. * InterpretVCDHeader.g -- Tree-walker which extracts id_code definitions and scopes SPI.py receives notifications from vcd_reader, and reconstructs SPI-protocol compliant messages (as strings of bits). ad9510spi.py takes in strings of bits, and interprets them as command messages for Analog Devices AD9510 clock chips. ----------------------- Copyright 2011 Carnegie Mellon University.
