Pioneering Safety-Critical Software: DENSO’s Journey with the LDRA tool suite

How DENSO improves soft­ware qual­i­ty while prepar­ing for future safe­ty stan­dards.

What is it about

Help­ing DENSO improve soft­ware qual­i­ty, ensure com­pli­ance with evolv­ing safe­ty stan­dards, and accel­er­ate inno­va­tion in next-gen­er­a­tion auto­mo­tive sys­tems.

DENSO at a Glance

DENSO Cor­po­ra­tion is a lead­ing glob­al sup­pli­er of advanced auto­mo­tive tech­nolo­gies, sys­tems, and com­po­nents for major automak­ers world­wide. Oper­at­ing in 32 coun­tries and regions with more than 112,000 asso­ciates, DENSO com­bines hard­ware and soft­ware exper­tise to deliv­er high-qual­i­ty, depend­able solu­tions for the auto­mo­tive mar­ket. The company’s Elec­tron­ic Sys­tems Busi­ness Group focus­es on devel­op­ing engine ECUs and inte­grat­ed cir­cuits for auto­mo­tive con­trol sys­tems, pro­mot­ing syn­er­gies between hard­ware and soft­ware develop­ment.

Balancing Performance, Safety, and Compliance

For DENSO, soft­ware qual­i­ty and depend­abil­i­ty in the field are essen­tial. At the same time, opti­miz­ing code size and ensur­ing real-time per­for­mance on resource-lim­it­ed tar­get hard­ware were crit­i­cal project require­ments. These needs are fur­ther ampli­fied in AUTOSAR envi­ron­ments, where the demands on soft­ware plat­forms are rig­or­ous. With the auto­mo­tive indus­try mov­ing toward safe­ty integri­ty stan­dards sim­i­lar to those in aero­space, DENSO faced the chal­lenge of lead­ing inno­va­tion while meet­ing increas­ing­ly com­plex com­pli­ance expec­ta­tions.

A Unified Approach to Software Analysis

DENSO adopt­ed the LDRA tool suite to apply uni­form analy­sis tech­niques and enforce con­sis­tent stan­dards across its soft­ware plat­forms. Lever­ag­ing LDRA’s proven soft­ware analy­sis meth­ods, DENSO was able to bench­mark third-party and inter­nal plat­forms, improv­ing over­all code qual­i­ty, depend­abil­i­ty, and com­pli­ance. The tool suite’s inte­gra­tion into develop­ment process­es also enabled the team to bal­ance qual­i­ty and effi­cien­cy while address­ing the demands of next-gen­er­a­tion auto­mo­tive sys­tems.

Stronger Software Quality and Compliance

By deploy­ing the LDRA tool suite, DENSO sig­nif­i­cant­ly improved soft­ware qual­i­ty, intro­duced a con­sis­tent approach to stan­dards com­pli­ance, and achieved sub­stan­tial cost and time sav­ings for both cur­rent and future projects. The uni­form plat­form of analy­sis not only enhanced depend­abil­i­ty but also sup­port­ed the company’s broad­er R&D efforts to pre­pare for evolv­ing safe­ty stan­dards.

“We have taken advan­tage of LDRA’s soft­ware analy­sis tech­niques to improve the qual­i­ty of our soft­ware plat­form. The LDRA tool suite is used as a bench­mark for other third-party and sim­i­lar soft­ware plat­form prod­ucts.”

— Mr. Aki­hi­to Iwai, Project Man­ag­er, DENSO Japan

Looking Ahead

DENSO plans to expand its use of LDRA’s test­ing and analy­sis tech­niques to fur­ther strength­en soft­ware val­i­da­tion in auto­mo­tive sys­tems. Build­ing on method­olo­gies long proven in aero­space, DENSO aims to pio­neer their appli­ca­tion in the auto­mo­tive indus­try, sup­port­ing the develop­ment of safer, more reli­able vehi­cles and prepar­ing for the wide­spread adop­tion of safe­ty integri­ty stan­dards.
