Ca­dence of­fers tech­nol­ogy to speed up de­sign cy­cle of ADAS

Auto components India - - COVER STORY - Text : Anusha B

Ca­dence De­sign Systems, the Cal­i­for­nia-based global leader in mak­ing Elec­tronic De­sign Au­toma­tion (EDA) tools re­de­fines the au­to­mo­tive safety path by of­fer­ing a proven In­tel­lec­tual Prop­erty (IP) that can speed up the de­sign cy­cle of the Ad­vanced Driver As­sis­tance chip (ADAS) de­signs. In In­dia, Ca­dence Ban­ga­lore fa­cil­ity com­prises field en­gi­neer­ing, global cus­tomer sup­port, R&D across plat­forms, mar­ket­ing, fi­nance, IT sup­port and hu­man re­source func­tions.

The tech­nol­ogy needs for com­mu­ni­ca­tion, au­dio, imag­ing and vi­sion are ad­dressed with Ca­dence’s Ten­sil­ica cus­tomis­able pro­ces­sors that im­ple­ment new al­go­rithms. The au­to­mo­tive com­pa­nies can im­ple­ment new al­go­rithms very ef­fi­ciently and save up to half of the sil­i­con and half of the power.

Sources in Ca­dence De­sign Systems said, “ADAS tech­nol­ogy sup­ports real time data pro­cess­ing for sen­sors and cam­eras, to en­able sen­sor fu­sion for safety-crit­i­cal systems. It also en­ables au­to­mated park­ing, lane de­par­ture and ve­hi­cle-to-ve­hi­cle com­mu­ni­ca­tion. Our IP is used in many ar­eas for driver’s as­sis­tance. Some of the ar­eas in­clude imag­ing and video as­sis­tance like traf­fic sign recog­ni­tion, voice and ges­ture recog­ni­tion, car2x and V2V com­mu­ni­ca­tion, eth­er­net and other stan­dards-based IP and other func­tional ver­i­fi­ca­tions. Con­sumers have re­acted very fa­vor­ably to our ADAS tech­nol­ogy that makes ve­hi­cles much more aware of the sur­round­ing driver en­vi­ron­ment and ren­der much safety at­tributes to drive.”

De­mand for these fea­tures is grow­ing as fast as the tech­nol­ogy is evolv­ing to pro­vide sen­sors, cam­eras, and sen­sor fu­sion soft­ware to per­form ob­sta­cle de­tec­tion and lane de­par­ture warn­ings. Also the soft­ware helps read au­to­mat­i­cally the street signs, dis­play speed lim­its, control speed and dis­tance to the car in the front, and per­form other vi­tal func­tions. In ad­di­tion, with the help of the com­pany’s tech­nolo­gies, cars can ex­change more and more in­for­ma­tion with other cars and their en­vi­ron­ment to make a smarter driving ex­pe­ri­ence. These essential driver as­sis­tance tech­nolo­gies are evolv­ing at a very fast pace. It is a chal­lenge to keep up with the tech­nol­ogy re­quire­ments for the race to­wards au­ton­o­mous ve­hi­cles or self-driving cars.

Func­tional chal­lenges

In an in­tel­li­gent elec­tronic sys­tem, un­ex­pected er­rors can lead to un­planned, un­ex­pected be­hav­ior in func­tional com­po­nents. This can be a po­ten­tially dan­ger­ous propo­si­tion for au­to­mo­tive man­u­fac­tur­ers, as well as a costly oc­cur­rence for con­sumer prod­uct de­vel­op­ers. Com­pli­ance to the lat­est safety stan­dards can be a la­bo­ri­ous and time­con­sum­ing process. There are now tech­nolo­gies that can au­to­mate the process of meet­ing func­tional safety re­quire­ments. From stay­ing up-to-date on the lat­est stan­dards to man­ag­ing all of the as­so­ci­ated data, and com­ply­ing with func­tional safety

re­quire­ments have been a time­con­sum­ing, man­ual ef­fort.

The com­pany is trans­form­ing this process by au­tomat­ing fault de­tec­tion and re­sult anal­y­sis for in­tel­lec­tual prop­erty (IP), sys­te­mon-chip (SoC), and sys­tem de­signs. “Built on the proven Ca­dence in­ci­sive ver­i­fi­ca­tion plat­form, our end- to-end func­tional safety so­lu­tion re­duces the au­to­mo­tive ISO26262 com­pli­ance ef­fort by 50%. The so­lu­tion is avail­able as part of our de­vel­op­ment suite,” sources said.

High­light­ing the chal­lenges while meet­ing func­tional re­quire­ments, a com­pany spokesper­sons said, “Meet­ing func­tional re­quire­ments is a crit­i­cal chal­lenge and it calls for check­ers which mon­i­tor the sys­tem and trig­ger er­ror re­cov­ery fea­tures when nec­es­sary. Re­dun­dancy is another at­tribute which pro­vides con­tin­u­ous func­tion in the event of er­rors. Hence it is oblig­a­tory for the safety en­gi­neers to align the de­vel­op­ment flow with the Tool Con­fi­dence Level (TCL). Func­tional ver­i­fi­ca­tion should take place at all lev­els of ab­strac­tion and for all sys­tem el­e­ments. Safety ver­i­fi­ca­tion, which mea­sures re­sponse of systems to un­de­sired or un­planned events, is another crit­i­cal step. Fi­nally to be in full com­pli­ance, safety en­gi­neers keep abreast of the record and re­port on all func­tional safety re­quire­ments”.

The elec­tronic de­sign au­toma­tion tool com­pany also un­veiled vir­tu­oso plat­form. Through this plat­form it of­fers de­sign­ers an av­er­age of 10x per­for­mance and ca­pac­ity im­prove­ment across the plat­form. The plat­form in­cludes new tech­nolo­gies within the Ca­dence Vir­tu­oso Ana­log De­sign En­vi­ron­ment (ADE) and en­hance­ments to the Ca­dence Vir­tu­oso Lay­out Suite to ad­dress re­quire­ments for au­to­mo­tive safety, med­i­cal de­vice and Internet of Things (IoT) ap­pli­ca­tions.

The next-gen­er­a­tion Ca­dence vir­tu­oso ADE prod­uct suite ad­dresses the chal­lenges that come with the emer­gence of new in­dus­try stan­dards, ad­vanced-node de­signs and the re­quire­ments for sys­tem de­sign, en­abling en­gi­neers to ex­plore, an­a­lyse and ver­ify de­signs to en­sure that de­sign in­tent is main­tained through­out the de­sign cy­cle. En­hanced data han­dling pro­vides up to 20X im­prove­ment in load­ing wave­form data­bases in ex­cess of 1GB and a 50X im­prove­ment in ver­sion­ing and load­ing set-up files into the en­vi­ron­ment.

The en­hanced Vir­tu­oso Lay­out Suite ad­dresses the most com­plex lay­out chal­lenges by of­fer­ing ac­cel­er­ated per­for­mance and pro­duc­tiv­ity for custom ana­log, dig­i­tal and mixed-sig­nal de­signs at the de­vice, cell, block and chip lev­els. Cus­tomers use Ca­dence soft­ware, hard­ware, IP, and ser­vices to de­sign and ver­ify ad­vanced semi­con­duc­tors, con­sumer elec­tron­ics, net­work­ing and telecom­mu­ni­ca­tions equip­ment, and com­puter systems.

Ca­dence has of­fices in Noida, Ban­ga­lore, Pune, Hyderabad and Ahmed­abad. Es­tab­lished in 1987, the Noida site is the largest Ca­dence R&D site out­side the US with over 1,700 em­ploy­ees. The com­pany’s 5 re­gions sup­port R&D work done in In­dia and fo­cus on de­vel­op­ing de­sign au­toma­tion so­lu­tions to ad­dress the needs of ad­vanced tech­nol­ogy nodes by lever­ag­ing its lead­er­ship in EDA tech­nol­ogy. Field Op­er­a­tions pro­vide sales and en­gi­neer­ing sup­port across all tech­nolo­gies.
