Abstract

The present invention permits a primary launch engine to display the names of, and information relating to, and cause the execution of diagnostic/test programs and/or batch-type routines for the silicon validation of microprocessors not only in existence at the time the primary launch engine is developed and compiled, but also, diagnostic/test programs and/or batch-type routines for the silicon validation of microprocessors that are developed and/or modified after the primary launch engine is developed and compiled without requiring modifications to, or the recompilation of, the primary launch engine. To do so, the present invention utilizes specialized data files consisting of one or more screen definition files and/or one or more script files wherein each screen definition file contains necessary menu structure and response information for each of the available diagnostic/test programs and wherein each of the script files contains sequencing and parameter information for each of the batch-type routines. These specialized data files are used by the primary launch engine to (i) display information pertaining to each of the available diagnostic/test programs and/or batch type routines and (ii) cause a general purpose computer to execute diagnostic/test programs and/or batch type routines selected by the user of the primary launch engine.

Claims

1. A method for controlling the operation of a general purpose computer to display information indicative of a plurality of separately executable diagnostic/test programs for validating the operation of a central processing unit and to cause the execution of at least one of said plurality of separately executable diagnostic/test programs, wherein said general purpose computer includes storage media and wherein said storage media includes said plurality of separately executable diagnostic/test programs, a primary launch engine, and at least one definition file, comprising:

executing said primary launch engine;

said primary launch engine extracting information from said at least one definition file indicative of said plurality of separately executable diagnostic/test programs and data necessary to execute said plurality of separately executable diagnostic/test programs;

said primary launch engine displaying information to said user indicative of said plurality of separately executable diagnostic/test programs, wherein said displaying information includes indicating to said user which of said plurality of separately executable diagnostic/test programs are compatible with said central processing unit;

said primary launch engine accepting an input from said user indicative of which of said plurality of separately executable diagnostic/test programs said user has selected for execution; and

said primary launch engine instructing said general purpose computer to execute at least one of said plurality of separately executable diagnostic/test programs in response to said input.

2. The method as recited in claim 1 further comprising said primary launch engine determining a type of central processing unit utilized by said general purpose computer.

3. The method as recited in claim 2 wherein the step of said primary launch engine extracting information from said at least one definition file includes:

said primary launch engine retrieving said at least one definition file;

said primary launch engine extracting a plurality of menu records from said at least one definition file, wherein each of said plurality of menu records includes information indicative of one of said plurality of separately executable diagnostic/test programs, data necessary to display and execute said one of said plurality of separately executable diagnostic/test programs, and a type of central processing unit for which said one of said plurality of diagnostic/test programs is designed to test;

said primary launch engine comparing the type of central processing unit associated with each of said menu records with said type of central processing unit utilized by said general purpose computer;

said primary launch engine adding said plurality of menu records to a dynamic menu-list, wherein each menu record in said dynamic menu-list includes a disable flag;

said primary launch engine setting said disable flag for a menu record when said comparing detects that said type of central processing unit associated with said menu record is not compatible with said type of central processing unit utilized by said general purpose computer.

4. The method as recited in claim 3 wherein the step of said primary launch engine displaying information to said user includes:

said primary launch engine retrieving a menu record from said dynamic menu-list;

said primary launch engine displaying a portion of said menu record from said dynamic menu-list, wherein said portion indicates that said one of said plurality of separately executable diagnostic/test programs associated with said menu record may be selected by said user for execution, wherein said displaying a portion of said menu record includes displaying an incompatibility indication if said display flag associated with said menu record is set, wherein said incompatibility indication informs said user that said one of said plurality of separately executable diagnostic/test programs corresponding to said menu record is not compatible with said central processing unit utilized by said general purpose computer.

5. The method as recited in claim 4 wherein the step of said primary launch engine accepting an input from said user includes:

said primary launch engine analyzing said input to determine which menu records said user has selected for execution; and

said primary launch engine examining said disable flags associated with said user selected menu record;

said primary launch engine requiring said user to select an override function for a user selected menu record if said disable flag associated with said user selected menu record is set, wherein said selection of said override function invokes execution of said one of said plurality of separately executable diagnostic/test programs corresponding to said user selected menu record whose disable flag is set.

6. The method as recited in claim 3, wherein each of said plurality of menu records also includes a domain indicator, wherein said domain indicator associated with a menu record determines whether said one of said plurality of separately executable diagnostic/test programs associated with said menu record resides internal to said primary launch engine or external to said primary launch engine;

said primary launch engine examining said domain indicator for a menu record which said user has selected;

said primary launch engine executing said one of said plurality of separately executable diagnostic/test programs associated with said menu record if said domain indicator indicates that said one of said plurality of separately executable diagnostic/test programs associated with said menu record resides internal to said primary launch engine;

said primary launch engine spawning said one of said plurality of separately executable diagnostic/test programs associated with said menu record if said domain indicator indicates that said one of said plurality of separately executable diagnostic/test programs associated with said menu record resides external to said primary launch engine.
