Our SPICE Circuit simulation facility have the capability to simulate Digital, Analog or Mix of them, transient and FFT (Fast Fourier Transform), Montecarlo sensitivity analysis and analog behavioral modelling. Over a 10,000 component library from a well known component manufacturer.

We offer design verification, simulation and circuit analysis. We also do circuit behavioral modeling including Spice MACRO modeling, and transistor device curve fitting and modeling. Our staff is skilled in Behavioral Modeling such as C/C++ and Matlab. We have developed a number of proprietary simulation EDA tools that we use in-house.

SPICEsim can simulate your circuits for you.

We specialize in batch processing of hundreds of corner cases over temperature and operating points. Our tools are set up, using Linux, for simulations to run 24/7 without the intervention of an operator. Data is readily captured, post processed and reduced automatically to render the final results of interest. We also bundle all the simulations into a report for the given design for future reference.

Besides our own EDA tools, we are experienced with Mentor, Cadence, SIMetrix/SIMPLIS and PSpice. We have had good success at automating these tools, hence saving much time and cost associated with GUI controlled simulations.

Further, our extensive system design experience can provide very valuable guidance in determining the reliability of simulation results. Experience in understanding and knowing when simulation results are false can prevent costly re-spins and schedule delays.

What is SPICE?

SPICE (Simulation Program with Integrated Circuit Emphasis) is a general-purpose open source analog electronic circuit simulator. It is a powerful program that is used in IC and board-level design to check the integrity of circuit designs and to predict circuit behavior.

Circuit simulation programs, of which SPICE and derivatives are the most prominent, take a text netlist describing the circuit elements (transistors, resistors, capacitors, etc.) and their connections, and translate this description into equations to be solved. The general equations produced are nonlinear differential algebraic equations which are solved using implicit integration methods, Newton's method and sparse matrix techniques.
