# Build ID Verilog Module Script
# Jeff Wiencrot - 8/1/2011
#
# Generates a Verilog module that contains a timestamp,
# from the current build. These values are available from the build_date, build_time,
# physical_address, and host_name output ports of the build_id module in the build_id.v
# Verilog source file.

	set buildTime [ clock format [ clock seconds ] -format %H%M%S ]
