VisSim

VisSim is a visually programmed block diagram tool for modeling, simulating and analyzing dynamic systems. It is developed by Visual Solutions.

VisSim is widely used in control system design and digital signal processing for multidomain simulation and design. Coupled with VisSim/C-Code, an addon product, VisSim performs code generation for real-time implementation of embedded systems. It can target small 16-bit fixed point systems like the Texas Instruments MSP430 using only 170 bytes of data RAM as well as larger 32-bit floating point processors like Texas Instruments C6713. This technique of simulating system performance off-line, and then generating code to run on the embedded system is known as "model based development". Model based development is becoming more widely adopted for production systems because it leads to shorter development cycles.

VisSim add-ons Include:

→ Physical layer communication system simulation
→ Frequency domain analysis (Bode, Root Locus, Nyquist)
→ OPC communication
→ Global parameter optimization
→ Real-time analog and digital I/O under Windows
→ Bit true fixed-point blockset for simulation and code generation
→ Code generation for on-chip peripherals like serial ports, CAN, PWM, QEP, Event Capture, SPI, ADC, DAC, and digital I/O
→ Electric motor simulation library for AC induction, Brushless DC, Stepper and Brushless DC motors
