DigitalcircuitdesignusingFPGAdevices,cannotonlysimplifythedesignprocessandcanreducethesizeandcostoftheentiresystem,increasingsystemreliability.Theydonotneedtospendthetraditionalsensealotoftimeandeffortrequiredtocreateintegratedcircuits,toavoidtheinvestmentriskandbecomethefastest-growingindustriesofelectronicdevicesgroup.DigitalcircuitdesignsystemFPGAdevicesusingthefollowingmainadvantages

（1）Designflexible

（2）Increasedfunctionaldensity

（4）Shorteningthedesigncycle

（7）Toreducecosts

Secondly,thesizeandFPGAdevicesallowautomationneedsplug-ins,reducingthemanufacturingsystemtolowercosts;

Again,theuseofFPGAdevicescanenhancesystemreliability,reducedmaintenanceworkload,therebyloweringthecostofmaintenanceservicesforthesystem.Inshort,theuseofFPGAdevicesforsystemdesigntosavecosts.
