Solutions
We provide solutions in the realm of hardware and software verification, in particular embedded services, virtualization, and portable stimulus (PSS). If you like what you see, then let’s showcase the solutions we offer to help shorten your product development cycle.
Device Driver Generator(DDGen)
Device Driver Generator (DDGen) from Vayavya Labs is a software platform designed for use by embedded system developers and SoC design engineers to automate device driver and firmware development. Use the specification and modify it as needed to generate the automatically the desired device drivers.
Features
Supports code generation for any class of embedded devices such as Ethernet, USB, Communication, memory, or any control type of devices including DMA controller, etc.
Generates driver code in ANSI C (C and header files) that an application programmer can use in their designs; Supports MISRA C compliance
Eclipse-based IDE
Out-of-the-box support for interface controller IPs from leading semiconductor IP providers
Supported Operating Systems: Linux, WinCE, VxWorks, MCAL, bare metal with a ready framework to quickly support other operating systems
Benefits
Enables formal capture of Hardware – Software Interface, a key requirement for ISO 26262 compliance
Automated & correct by construction – device driver code
Over 40% reduction in costs and time-to-market
4x-6x lesser effort for new board / OS
Case Studies
DeMystifying DDGen
Debugging of DDGEN Generated Device Driver Code
Virtual Platforms & SystemC modeling
We develop virtual platforms to simulate the target hardware on which the software is intended to run. It can comprise of a number of virtual models or a prototype, each of which is a high speed software model of a physical product that can be presented, analyzed, and tested from a real life system perspective, including tests that are not possible to run on the physical hardware. The virtual platform developed can be scaled as needed and can be used to augment the traditional RTL-to-GDSII flow. Virtualization enables among other things, pre-silicon software development & testing, architectural exploration, performance & power optimization, SoC & system verification and hardware-software partitioning.

Hardware-software Interface Management (HSI)
For most semiconductor design companies, the existing communication between SoC design teams and software teams through data sheets, programming guide/book, Word documents or Excel spreadsheets often results in a lot of ambiguities. These misinterpretations can prove costly while developing bare metal or OS based drivers resulting in potential slips to design schedules.
Vayavya’s HSI® management enables SoC design teams to capture the programming interface of a device in a formal manner. This HSI® spec then serves as a golden reference for various teams across the design teams. The HSI specification can also be used as a method for realizing tests using portable stimulus (PSS) or generating device drivers automatically using DDGen from Vayavya Labs
Portable Stimulus (PSS)
The PSS standard helps verification engineers define system level tests such that the tests are portable between verification levels – IP, subsystem, system – and verification platforms (simulation, emulation virtual platform, etc.). One of the major challenges that verification engineers face with PSS is in converting these high-level test representations into something that can run at one of those levels, on one of those platforms. This stage of PSS or the Test Realization layer requires software and verification engineers to implement the hardware-software interface which is not only an effort-intensive and error-prone work but also requires domain knowledge of the device(s).
At Vayavya Labs we provide solutions to automatically generate the device drivers using the APIs and middleware defined in the OpenHSI initiative. We also provide services for custom development of device drivers and software stack needed for realizing the PSS tests.
Automotive
From connected cars to autonomous vehicles, it is no more just a mechanical/electric assembly of components. Software and electronics are taking over automobiles with a growing shift towards autonomous/self driving vehicles, infotainment, emphasis on critical safety features especially in software and standardization of embedded software platforms. It is estimated that there are millions of line of code in a car.
Vayavya Labs is a member at ASME and is uniquely placed to offer key embedded software solutions. We also offer ADAS & autonomous vehicle validation services.
Features
We provide custom development of MISRA-C compliant drivers for the MCAL layer, automated testing & verification of MCAL Drivers and implementation of Adaptive AUTOSAR. We also provide technical assessment & evaluation of embedded platforms based on customer’s needs and requirements

Automotive Grade Linux (AGL)
We provide services around board bring-up, OS porting and customization
Communications & Connectivity
The surge of platforms such as Android, iOS, AWS etc. cloud-based delivery and enhanced data network has resulting in re-writing or developing anew, a lot of applications. This has resulted in the proliferation of new devices, edge-based computing platforms. Vayavya Labs offers solutions including endpoint software stacks, product compliance or pre-compliance testing for emerging networking technologies such as Time-Sensitive Networking (TSN) a.k.a Audio Video Bridging (AVB).
The AVB endpoint stack is based on OpenAvnu, one of the most popular standards and preferred by many in the industry for their AVB equipment.
