Location of th e System Files

When the logic analysis system is conf igur ed at Hewlet t -Packar d with the a ppropriat e m odules, the system files for th e mainfram e and individual m odules were loa ded onto the hard disk drive in the subdi r ector y called "SYSTEM ". It is rec om m ended that if new m odules are a dde d or any system file re visi ons occur, th ey be loade d onto the hard disk drive in this subd i rectory.

H ow ever, if you want system files on a flexible disk, us e th e appropriat e disk operat ions, such as st ore or copy, to stor e all req u ired system files on a flexible disk.

What Files ar e Required on a System Disk?

A system disk consists of th e sof tware require d to opera t e the mainfram e and each m odule in the system . For the mainfram e, th is is th e file SYSTEM _ of th e file typ e 16500B_s ys t em . For th e individua l m odules , it is th e file SYS_XXX of th e file typ e XXXXXX_system. The th ree charact er s (XXX) in th e filenam e r epr es ent the identificat ion code for each indivi dual m odule. The si x charact er s (XXXXXX) in the file type r epr esent the produc t model num ber for each m odule.

What is a system perform ance ver ificat i on disk?

A system perform ance ver ificat ion disk is a disk th at cont ains all the perfor m ance verificat ion software required to run th e perform ance ver i ficat i on tests for th e HP 1650 0B Logic Analysis System and the correspon d ing m odules conf igur ed in th e system . This com posite disk is found in each software pouc h. For more infor m ation on th e perfor m anc e ver i ficat i on tests, refer to the

Displ ay Color Se lection

In the HP 16500B, color s aves time a nd prevent s errors by clar ifying the displ ay, making it easier to distinguish one major area from anot her.

The color sel ection featur e of the HP 16500 B allow s you to cust om ize displ ay col or s , which improves cont rast and les sens eye fat igue caused by your operating environm ent. If you ar e color- blind to cer t ai n col ors, are oper a ting in a difficult light environ m ent, or don’t like the default color s , you can quickly and easily change them .

The Color M odel

The HP 16500B use s th e H SL color model (H ue, Saturation, a nd Lum inosity) . This model is ver y ef fective for inter act i ve color sel ect i on. Similar in concept to the method use d by ar t i st s for mixing pa ints , pur e hues ar e sel ected, and th en white and black ar e mixed to dilute the col or or dar ken it.

Hue is th e pure color . 0 is re d , 33 gr een, and 67 blue. The sel ect ion

ran ges from 0 to 100. Sa tura tion is the ratio of th e pure col or mixed with white (0 to 100% )

•

Lum inos ity is the br ightness pe r unit area (0 to 100% ).

•

The figure on th e nex t page show s a cyl indrical r epr esentation of the HSL model (H ue, Sa tur ation, a nd Lum inosity ). Hue is the angul ar coordi nate, Sa tura tion is the rad ial coordinate, a nd Luminosity is th e altitude above the polar coor di nate plane.

The cylinde r rests on a black plane (Lum i nos ity = 0% ) and ex te nds upw ard. As you increase in altitude, you increas e lum inos ity, which r epr es ents an inc rea se in brightness. W henever lum inosity is zero, the values of saturation a nd hue do not matter . Zero lum inos ity is black, and 100% lum inos ity gives you th e pure color .

White is th e cent er of th e to p of the cylinder (Lum inosity = 100% , Sa tur ation = 0% ) . The cent er line of the cyl inder (Sat uration = 0% ) is a line which connect s the cent er of the black plane (Lum i nos ity = 0% , Saturation = 0% ) with white (Lum i nosity = 100% , Saturation = 0% ) through a seri es of gr ay steps (Lum i nosity from 0% to 100% , Satur ation = 0% ) . W henever saturation is 0% , the val ue of hue does not matter . Zero satur ation is white, and 100% saturation gives you the pure color .

A glitch is defined as two or more tran sitions betw een the sam ples of a timing analyz er that cr oss th e logic thres ho ld. A timing anal yzer can trigger on a glitch a nd capt ur e it, but doesn’t have the vol t age or timing resolution to look at th e glitch in detail. On th e ot he r hand, an oscillos cope can acqui re w avef or m s with a gr eat deal of reso lution, but it can’t trigger on glitches, com binations of glitch e s, or patte rn s.

To analyze a glitch , use a timing anal yz er and an os cilloscope inter act ivel y. Set up the timing anal yz er to trigger on a glitch and when the timing anal yz er triggers , capt ure the glitch with th e os cilloscope. Then us e the os cillos c ope to look at the w avef or m param eters of th e glitch, including its width, s hape, a nd am plitude .

For this inte rm odule m easurem ent, you ar e using the trigger ing capabi lities of the timing analyz er and the acquisi tion capabi lities of th e os c illos cope.

Usually, softw are designer s want to look at the pr ogr am flow of the micr oprocess or system around an asynchr onous event .

A state anal yz er , c oupled with a prepr ocess or and an invers e as sem bl er , is useful for t r aci ng th e flow of a micr oprocess or prog ram . A timing anal yz er or an os cillosc ope is designed to trigger on asynchr onous event s like edges .

In this exam ple, use an os cilloscope with a sam pl e rate fast er th an the micr oprocess or cl ock to trig ger on the asynchronous event and to ar m the state anal yz er . Then us e the state anal yz er to check the a ddress of the inte rrupt ro u tine. You may also us e the state anal yz er to see if the micr oprocess or is properly servi cing interrupts and returning to th e cor rect a ddress af ter each interrupt routine.

Interrupt Handling Example

Set up the os cillos c ope to trigger on the as ynchronous interrupt line. This is usually an e dge- sensitive line on which the oscillos cope can trigg er .

The st ate anal yz er shou ld be ar m ed by the os cillos cope. Set th e state analyz er to trigger on all “d o n ’t cares ” and it will capt ure th e interrupt service routine when the ar m signal is received. For this interm odule m easurem ent , ar m i ng th e st at e analyzer with the osc illosc ope allow s a sof t w are des igner to t r ack the flow of a microprocess or pr ogr am around a hard w are interrupt.

During system devel opm ent , designer s ar e often faced with verifying a part of a design when th e input si gnal s for that part ar e unavailabl e. Here ar e som e com m on exam ples of this pr oblem :

The trad itional sol ution is to us e word gener ator s to em ulat e the missi ng part of the de sign, and to use logic anal yz er s and os c illos copes to capt ur e the system response.

Unfortunately, designer s ar e often faced with an aw kw ar d sol ution of stacki ng sever al boxes on top of each ot her , with a maze of cabl es tying them t ogether, a nd a different interface for each instrum ent.

The pa tte rn gener at or in the HP 16500B can act as the stack of word gener at ors in th is pr oblem . Sta te, timing, and analog m odules can all be us e d to capt ure the response of th e system .

The pa tte rn gener at or is loaded with the prope r patter ns and when it start s sending pa tte rn s, it s e nds an ar m si gnal over the interm odule bus .

The acqui sition m odules ar e ar m ed from the pa ttern gener ator m odule and set to trigger on th e appropriat e event in the system .
