Logic simulator system using both free-format display format and stream

Abstract

In a logic simulation system, a first management table manages time-series data of signal values for each signal terminal, constituting logic simulation result information. A setting unit sets one or a plurality of display formats for logic simulation result information, permitting a desired display format, through an interactive communication with users. A second management table for manages a display manner of a free-format display format, set by the setting unit. A third management table manages a display format of a stream display format, which is a time-series display format of logic simulation result information. A result display control unit specifies logic simulation result information at the present display time in the free-format display format, with reference to respective management data in the first and second management tables to thereby display the specified logic simulation result information, and for specifying logic simulation result information, including the present display time, in the stream display format with reference to the management data in the first management table and management data in the third management table. The system thus exactly displays logic simulation result information required by users, and thus effectively executes a logic simulation analysis.
