Soft­ware-de­fined in­stru­men­ta­tion

s the com­plex­ity of prod­ucts con­tin­ues to in­crease, their test­ing be­comes much more chal­leng­ing. Test en­gi­neers now re­quire test sys­tems the wide va­ri­ety of tests that must be per­formed on a sin­gle prod­uct while be­ing scal­able enough to en­com­pass a larger num­ber of tests as new func­tion­al­ity con­tin­ues to be added.

“In­creas­ingly, the func­tion­al­ity of the soft­ware em­bed­ded in them. This is chal­leng­ing for many test en­gi­neers be­cause most stand­alone in­stru­ments can­not change their func­tion­al­ity as fast as changes in the de­vice un­der test and em­bed­ded in the in­stru­ment. Thus test en­gi­neers are turn­ing to a soft­ware so that they can quickly cus­tomise their needs and in­te­grate test­ing di­rectly into the de­sign process,” says Eric Starkloff, di­rec­tor of NI Test Prod­uct Mar­ket­ing.

Thakare shares two ma­jor ad­van - tion: “First, it can dra­mat­i­cally re­duce the num­ber of hard­ware com­po­nents in all the mixed-sig­nal de­signs, which means smaller chip size for sys­tem-onchip im­ple­men­ta­tion. Sec­ond, it can pro­vide au­to­matic ad­just­ment or com­pen­sa­tion for cir­cuit com­po­nent vari­a­tions due to tem­per­a­ture de­pen­dence, age­ing and man­u­fac­tur­ing tol­er­ances.”

looks to be­come an es­sen­tial com­po­nent of scal­able and highly per­form­ing test sys­tems. Singh agrees by say­ing, “We pre­dict a bright fu­ture for soft­ware­de­fined in­stru­men­ta­tion. Soft­ware vir­tual in­stru­ments, are mod­u­lar hard - cus­tom data pro­cess­ing us­ing com­mon is use­ful for elec­tronic de­vices like ad­vanced nav­i­ga­tion sys­tems and com­mu­ni­ca­tion de­vices like smart­phones to in­te­grate di­verse ca­pa­bil­i­ties and adopt new com­mu­ni­ca­tion stan­dards.”
