1.0 ABSTRACT
THIS DECSYSTEM KL10 ADVANCED INSTRUCTION DIAGNOSTIC IS THE
SECOND IN A SERIES OF DECSYSTEM KL10 ADVANCED PROCESSOR
DIAGNOSTICS.
THE DIAGNOSTIC PERFORMS LOGIC TESTING OF THE PROCESSOR
AND MICRO-CODE DOUBLE PRECISION FIXED POINT INSTRUCTIONS:
DADD, DSUB, DMUL, DDIV.
2.0 REQUIREMENTS
2.1 EQUIPMENT
A DECSYSTEM KL10 EQUIPPED WITH A MINIMUM OF 32K OF MEMORY
CONSOLE PROCESSOR
CONSOLE TELETYPE
LOAD DEVICE
2.2 STORAGE
THE PROGRAM RUNS WITHIN 32K OF MEMORY.
2.3 PRELIMINARY PROGRAMS
PREVIOUS PROCESSOR DIAGNOSTICS
3.0 PROGRAM PROCEDURES
3.1 LOADING PROCEDURE
****** NOTE ******
THIS DIAGNOSTIC REQUIRES THAT THE DECSYSTEM KL10 SUBROUTINE
PROGRAM BE RESIDENT IN THE DECSYSTEM KL10.
FOLLOW THE APPROPRIATE DIAGNOSTIC LOADING PROCEDURES.

3.2 STARTING PROCEDURE
A. SELECT OPERATIONAL CONSOLE DATA SWITCH SETTINGS (REFER TO
4.0 DATA SWITCH FUNCTIONS).
B. EXEC MODE
STAND-ALONE STARTING ADDRESS IS 30000.
C. USER MODE
RUN UNDER "DIAMON".
THE FOLLOWING QUESTIONS WILL BE ASKED TO SELECT THE
OPERATIONAL SWITCHES:
TELETYPE SWITCH CONTROL ? 0,S OR Y (CR) -
IF THE OPERATOR TYPES "Y", THE FOLLOWING QUESTIONS
ARE ASKED AND THE OPERATOR RESPONDS BY TYPING THE
ANSWER AS SIX OCTAL DIGITS REPRESENTING THE DESIRED
SWITCH SETTINGS.
SPECIFY LH SWITCHES IN OCTAL-
SPECIFY RH SWITCHES IN OCTAL-
IF THE OPERATOR TYPES "0", ZERO'S ARE USED FOR
THE SWITCH SETTINGS.
IF THE OPERATOR TYPES "S", PREVIOUSLY SET SWITCHES
ARE USED. THIS IS ONLY VALID UPON RESTARTING OF AN
INTERRUPTED PROGRAM.

3.3 OPERATING PROCEDURE
A. TO THROUGHLY TEST ALL HARDWARE, ALL TEST CONTROL DATA
SWITCHES SHOULD BE SET TO 0.
B. WHEN DEBUGGING HARDWARE, SET SWITCHES TO 0. ALLOW THE
TELETYPE TO PRINT THE ERROR MESSAGES. THIS ALLOWS THE
PROGRAM TO RUN A COMPLETE PASS AND THEN THE ERROR MESSAGES
MAY BE CORRELATED TO QUICKLY DIAGNOSE THE FAILURE. IF A
HARDWARE PROBLEM IS SUCH THAT THE ERROR MESSAGES, AFTER THE
FIRST ONE, HAVE NO MEANING (FIRST ERROR CAUSES ALL FOLLOWING
TESTS TO FAIL) SET THE LOOP ON ERROR SWITCH AND RESTART THE
TEST FROM THE BEGINNING. THE FIRST FAILURE WILL THEN CAUSE
THE PROGRAM TO ENTER A LOOP SUITABLE FOR SCOPING.
THE ERROR MESSAGE USED IN CONJUNCTION WITH THE LISTING AND
SCOPING IF NECESSARY SHOULD ALLOW THE FAILING CONPONENT TO
BE ISOLATED AND REPLACED AND/OR REPAIRED.
C. WHEN TAKING MARGINS, SET DATA SWITCHES 'NOPNT' AND 'DING'.
THIS WILL INHIBIT PRINTOUT BUT WILL ALLOW THE TELETYPE BELL
TO BE RUNG WHEN A ERROR OCCURS. IF THE MARGIN OBTAINED IS
UNACCEPTABLE, THE OPERATOR MAY REVERT TO STANDARD SWITCH
SETTINGS FOR DEBUGGING PURPOSES.
D. ERROR INFORMATION MAY BE OBTAINED QUICKLY BY PRINTING
ERRORS ON THE LINE PRINTER.
E. IN THE EVENT OF A PRINT ROUTINE FAILURE THE 'NOPNT' SWITCH
AND THE 'ERSTOP' SWITCH MAY BE SET TO INHIBIT PRINTOUT BUT
HALT THE PROGRAM POINTING TO THE ERROR.

5.0 ERRORS
ERRORS ARE PRINTED ON THE TTY OR LINE PRINTER. THE ERROR PRINTOUT
CONTAINS THE TEST TITLE, THE PC OF THE FAILURE, ERROR NUMBER AND
THE CONTENTS OF AN APPLICABLE AC.
THE PC VALUE IS USEFUL IN RELATING THE FAILURE TO THE LISTING.
THE ERROR NUMBER IS PROVIDED SUCH THAT AN ERROR DICTIONARY MAY
BE MADE AT SOME FUTURE DATE.
IF AN AUDIO INDICATION OF A CONTINUING ERROR IS DESIRED THE 'DING'
SWITCH MAY BE SET.
6.0 ITERATION COUNTER
THE ITERATION COUNT OF THE PROGRAM IS PRINTED BY THE CONSOLE PROCESSOR.
7.0 CYCLE TIME
THE CYCLE TIME OF THE PROGRAM IS IN THE MILLISECOND RANGE AND IS
THEREFORE SUITABLE FOR TAKING MARGINS, VIBRATION TESTS, ETC.

8.0 OPERATIONAL VARIATIONS
A. DIAGNOSTIC MONITOR
THE PROGRAM IS USABLE WITH THE DIAGNOSTIC MONITOR TO PROVIDE
RELIABILITY TESTS, ACCEPTANCE TESTS, AND/OR TO PROVIDE A QUICK
METHOD OF ISOLATION OF A FAULT TO A PARTICULAR AREA OF THE
PROCESSOR. CERTAIN PROCEDURES ARE USED WHEN THE PROGRAM IS
USED IN THIS MANNER. THEY ARE:
1. THE DIAGNOSTIC MONITOR TRANSFERS CONTROL TO THE PROGRAM
AND STARTS IT AT LOCATION 30002.
2. MONCTL - LOCATION 30043 IS USED AS THE DIAGNOSTIC MONITOR
CONTROL WORD.
LH = 0, STAND-ALONE OPERATION
-1, RUNNING UNDER DIAGNOSTIC MONITOR
RH = RIGHT HALF OF CONSOLE SWITCHES IF UNDER
DIAGNOSTIC MONITOR CONTROL.
B. USER MODE
TO OUTPUT THE PRINTED ERROR MESSAGES TO A USER SPECIFIED
DEVICE IN USER MODE, ASSIGN THE DESIRED OUTPUT DEVICE TO
DEVICE NAME 'DEV' AND SET SWITCH 'PNTLPT'. THE PHYSICAL
DEVICE USED CAN BE ANY DEVICE THAT CAN ACCEPT ASCII OUTPUT
FORMAT SUCH AS LPT, DSK, DTA, ETC. THE CORRESPONDING
OUTPUT FILE IS 'DFKCB.LPT'
EXAMPLE DEVICE ASSIGNMENT:
.ASSIGN DSK DEV
IN USER MODE THE PROGRAM WILL MAKE 10(8) PASSES AND THEN
RETURN TO SMMON COMMAND MODE.
MAINDEC-10-DFKCB.TXT
PAGE 9
8.0 OPERATIONAL VARIATIONS (CON'T)
THE OUTPUT FILE (IF USED) MAY THEN BE LISTED BY USING THE
NORMAL MONITOR COMMANDS (PRINT, LIST, TYPE, PIP, ETC.).
IF THE PROGRAM IS ABORTED BEFORE COMPLETION (BY ^C, ETC.) THE
OUTPUT FILE MAY BE CLOSED BY USING THE MONITOR 'REENTER'
COMMAND.
C. SYSTEM EXERCISER
START ADDRESS IS 30003. DATA SWITCHES ARE PRESTORED IN
'SWTEXR' LOC 30023.
9.0 MISCELLANEOUS
THE NON-EX-MEMORY AND PARITY STOP SWITCHES SHOULD BE RESET
(0). THESE ERRORS, ILLEGAL UUO'S AND OTHER ERRORS OF THIS
TYPE ARE HANDLED BY PRINTOUT ON THE TELETYPE.
