J&D Tech CodeViser is a JTAG emulator for embedded software development on automotive MCUs and Arm processors. With the CVD (CodeViser Debugger) software on a Windows PC it debugs C, C++ and assembly code at source level, controls multi-core SMP, AMP and big.LITTLE targets, programs flash, and is OS aware for Linux, Android and common RTOSs. CVD editions cover 32-bit and 64-bit Arm, Infineon TriCore (AURIX), RISC-V, Andes and Qualcomm QDSP6. Pertech, a J&D Tech representative, sells and ships it worldwide.

Frequently asked questions
What is CodeViser?
CodeViser is J&D Tech’s JTAG emulator. Together with the CVD debugger on a Windows PC it debugs embedded software, controls multi-core targets and programs flash.
Which CVD edition do I need?
Choose by processor: CVD for 32-bit Arm, CVD64 for 64-bit Arm (Armv8), CVD TriCore for Infineon AURIX, CVD Risc-V, CVD_ANDES for Andes cores and CodeViser QDSP6 for Qualcomm DSPs. Pertech will confirm the edition for your chip.
Does it support AURIX automotive MCUs?
Yes, through the CVD TriCore edition. TriCore is the CPU core of Infineon’s AURIX family; J&D Tech’s brochure lists TriCore TC2xx.
Is multi-core debugging an extra cost?
No. J&D Tech states that no additional license is needed for multi-core debugging in CVD.
Can it program flash?
Yes: NOR, NAND, OneNAND, moviNAND, iNAND and the internal flash of many chipsets, with device and script files for each flash. Several CodeVisers can program several boards at once.
Does it run my .cmm scripts?
CVD is compatible with .cmm script files as well as its own .csf scripts.
