Chu, Ming-Cheung2014-03-142014-03-141992-07-06etd-10062009-020040http://hdl.handle.net/10919/45005Timing hazards are common problems found in logic circuits. A new integrated hazard detection system (HDS), which is implemented in VHDL, is proposed to detect the static, the dynamic, and the function hazards in any logic circuit that is described structurally in VHDL. This system adopts the IEEE VHDL Model Standard Group 1076-1164 Nine-Valued Multiple-Valued Logic package. Without any designer-supplied arbitrary input test patterns, the system predicts which input combinations will cause hazards, reports what type of hazards, and provides detailed timing information on the hazards in the combinational logic circuit with fixed gate delays.viii, 238 leavesBTDapplication/pdfenIn CopyrightLD5655.V855 1992.C58Logic circuitsLogic programmingVHDL (Computer hardware description language)Hazard detection with VHDL in combinational logic circuits with fixed delaysThesishttp://scholar.lib.vt.edu/theses/available/etd-10062009-020040/
