About Us


Mirabilis Design is a Silicon Valley based software company providing system architecture exploration and communication platform for electronics, embedded software and semiconductors. Mirabilis Design is a California-based, privately-held, minority-owned small business. Started by experts in the field of architecture exploration and digital simulation technology, Mirabilis Design products empower design teams to create the right product using early architecture studies and analysis. The company has developed an innovative system design methodology that enables extensive and quick product specification trade-off by accelerating model construction, ready-to-use reports and enable uniform communication between teams.
Our products and services are used by 55 of the largest electronics and semiconductor companies in the world. Engineering uses our solution to design the system specification and validate the non-functional requirements. Marketing uses the same models as a early demonstrator of system behavior, validate against the standards and generate activity data for certification.


VisualSim is the graphical modelling and simulation software for the rapid exploration of architectures to optimize the product specification for functionality, power and performance. Using prebuilt modelling libraries in VisualSim, engineers assemble models of their proposed system in a graphical editor. Users’ instantiate pre-defined analysis reports in the model and schedule simulation experiments over a wide-range of attribute values. The output reports provide recommendations that are used by the designers to arrive at a system specification that is optimized to meet performance requirements at the right price, weight, reliability and energy consumed. VisualSim is used by Systems Engineers, Architects, Software Designers and Program Managers.


VisualSim Architect is being used by our customers to eliminate risk, maximize productivity, enable team communication/ coordination/ management, maximize reuse and create optimal products in a very small amount of time. Our customers have found adoption of VisualSim to be easy and their time-to-results to be very short. The benefits of VisualSim have been realized not only by individual engineering teams, but also their managers who use the solution to optimize the coordination of their team’s efforts thereby minimizing product time-to-market. The use of VisualSim in conducting system-level design represents a proven industrial solution which maximizes productivity and enables rapid convergence to an optimal, and therefore, highly competitive product.

Why Choose Us

    • Accelerate time-to-market

      Eliminate system performance barriers and increase confidence in the product specification using the modeling library and analysis tools that are provided in VisualSim.

    • Visualize the proposed system architecture

      Refine the timing, power and behavior performance of the system to meet the customer requirements at the best cost. The innovative modeling methodology and the vast systems engineering experience of VisualSim enable the detailed evaluation of complex electronic architectures

    • Reduce system modeling effort and time

      Our technology has been built for rapid product exploration, system validation and design space experimentation. The pre-built modelling library, application-specific templates, detailed technical support and extensive reports provide instant feedback on your system feasibility, reliability, safety, performance, energy-efficiency and quality.

    • Validate “Mission Assurance” and “Integrity of Design“

      Significantly reduce the risk of failure through dynamic system simulation… test out everything prior to implementation

    • Collaborative design

      Simulatable specification to share the specification via a web-based simulatable specification to work interactively with remote teams and to extend early system modelling use into marketing, partnership and resource planning.

Management Team

The Mirabilis Design team is composed of veterans of electronics system-level design and systems engineering. All team members have advanced scientific degrees and/or MBAs.

Deepak Shankar, CEO and has over 18 years of experience in development, sales and marketing of system-level design tools. Prior to Mirabilis Design, Mr. Shankar was VP of Business Development at MemCall, a fabless semiconductor company and SpinCircuit, a supply chain joint venture of HP, Cadence and Flextronics. Prior to that, Deepak spent many years in product marketing at Cadence Design Systems. Mr. Shankar has an MBA from UC Berkeley, MS from Clemson University and BS from Coimbatore Institute of Technology, both in Electronics and Communication.

Darryl Koivisto, Ph.D. is the CTO and has over 30 years of experience as an Architect, Program Manager and modeling expert. Prior to Mirabilis Design, Mr. Koivisto held a number of roles with increasing responsibility and was most recently the Principal Modeling Consultant at Cadence Design Systems. Prior to Cadence Design System, Darryl held Project Management roles at Ford Aerospace where he managed large satellite projects for NASA. Previously, Mr. Koivisto was a Chip Architect at Signetics, now Philips Semiconductor, and I/O Architect at Amdahl. Mr. Koivisto has a DBA from Golden Gate University, MS from Santa Clara University and BS from California Polytechnic University, San Luis Obispo.
