PDFOverview
Traditional SPICE simulators are limited to analog and digital components known to the original Berkley SPICE engine. Thanks to the patented co-simulation engine of NI Multisim, designers and educators can easily combine microcontrollers, VHDL-based components and RF components with their SPICE-based circuits in order to extend the breadth of their circuit simulation.
The Co-Simulation engine is completely integrated in NI Multisim so a user doesn’t need to know or learn something new. The co-simulation engine shares data between the different component types and produces one simulation result to the user, hence enable the user to simulate a complete system.
NI Multisim RF
Most SPICE models are unreliable for RF designs because at these frequencies simulated SPICE behavior departs from datasheet and textbook values. NI Multisim RF overcomes this limitation by providing a library of SPICE models designed to be accurate at high frequencies.
- NI Multisim RF supports
- Interdigital Capacitors
- Microstrips
- Transmission Lines
- Spiral Inductors
- Pin & Tunnel Diodes
- RF BJTs & MOSFETs
- Waveguides
- Model generation using the Model Maker
NI Multisim MCU Module
The National Instruments Multisim MCU Module adds microcontroller unit co-simulation capabilities to Multisim, allowing you to include a microcontroller, programmed in assembly or C code, within your SPICE modeled circuit. The MCU Module can be used with any of Multisim’s virtual instruments for a complete system simulation, including the microcontroller and all connected analog and digital SPICE components.
- The NI Multisim MCU Module supports
- Intel®/Atmel® 8051/8052
- Microchip PIC16F84a
- C and Assembly language
- Advanced debugging tools
- External RAM and ROM
- Keypads and serial terminal
- Graphical and alphanumeric LCDs
MultiVHDL
MultiVHDL can be used as a stand-alone application, or together with Multisim’s SPICE simulator using patented co-simulation. It is perfect for teaching HDLs, digital logic, programmable logic design or for creating simulation models for complex digital IC’s not practically modeled in SPICE. Co-simulation allows you to introduce VHDL modeled components into mixed-mode circuits and to demonstrate the performance of a FPGA/CPLD in the real (SPICE modeled) circuit in which it will be used.
- MultiVHDL supports
- IEEE 1076-93 (IEEE 87)
- IEEE 1164 (IEEE 93)
- Module Wizard
- State Machine Editor
- On-the fly error detection
- Graphical Test Bench Editor
- Graphical Waveform Viewer
