VisSim - system simulation and optional C-code generation of electrical, process, control, bio-medical, mechanical and UML State chart systems. Vortex (software) - a complete simulation platform featuring a realtime physics engine for rigid body dynamics, an image generator, desktop tools (Editor and Player) and more. Also available as Vortex ...
A cycle-accurate simulator is a computer program that simulates a microarchitecture on a cycle-by-cycle basis. In contrast an instruction set simulator simulates an instruction set architecture usually faster but not cycle-accurate to a specific implementation of this architecture; they are often used when emulating older hardware, where time precision is important for legacy reasons.
An instruction set simulator (ISS) is a simulation model, usually coded in a high-level programming language, which mimics the behavior of a mainframe or microprocessor by "reading" instructions and maintaining internal variables which represent the processor's registers.
There is a freely available MIPS32 simulator (earlier versions simulated only the R2000/R3000) called SPIM for use in education. EduMIPS64 [50] is a GPL graphical cross-platform MIPS64 CPU simulator, written in Java/Swing. It supports a wide subset of the MIPS64 ISA and allows the user to graphically see what happens in the pipeline when an ...
Specifically, the input can be a trace collected from an execution of program on a real microprocessor (so called trace-driven simulation) or a program itself (so called execution-driven simulation). A trace-driven simulation [1] reads a fixed sequence of trace records from a file as an input. These trace records usually represent memory ...
The 8-bit f field determines the address in combination with the a bit and the 4-bit bank select register (BSR). If a=0, the BSR is ignored and the f field is sign-extended to the range 0x000–0x07F (global RAM) or 0xF80–0xFFF (special function registers). If a=1, the f field is extended with the BSR to generate the 12-bit address.
[1] A simulator program is intended to execute the bits in the same way as the electronics, and allows much more freedom to debug the microprogram. After the microprogram is finalized, and extensively tested, it is sometimes used as the input to a computer program that constructs logic to produce the same data.
MPsim is a fast compiled simulator with full support for Verilog, SystemVerilog and SystemC. It includes Designer, integrated Verilog and SystemVerilog debugging environment and has built-in support for multi-cpu simulation. PureSpeed: Frontline: V1995: The first Verilog simulator available on the Windows OS.
