Printed Circuit Card Reverse Engineering Spice Simulation Program
When printed circuit card reverse engineering is being processing, circuit system design engineers will occasionally requires to analyze partial circuit voltage and current relationship in the system from details, at this right moment the transistor level simulation will be required, this kind of simulation algorithm use the most basic components and transistor in the circuit model when printed circuit card reverse engineering.
Calculate each one of the I/V relations on all of the joints according to the time relations when printed circuit card reverse engineering simulation. And this is also one of the most precise and time consuming way amongst all of the simulation methods in printed circuit card reverse engineering.
SPICE (Simulation program with integrated circuit emphasis) from printed circuit card reverse engineering is the most popular and widely accepted circuit simulation program, and each one of the software manufacturers provide different versions of SPICE software when reverse engineering printed circuit card, however, their simulation cores are all the same in essentials while differing in minor points, and there is one common place for all of these softwares is they all apply the SPICE simulation algorithm which is developed by BERKELEY university in California.
SPICE can carry out nolinear direct current analysis on the circuit when reverse engineering printed circuit card, nolinear transient analysis and linear alternative current analysis when printed circuit card reverse engineering. And the components which are being analyzed in the circuits include resistor, capacitor, inductor, mutual inductor, isolated voltage source, isolated current source, various linear controlled source, transmission line and other active semiconductors from PCB reverse engineering. SPICE can build the semiconductor model, user just need to choose the proper models and parameters.
