In particular, a piece of software that simulates a microprocessor executing a program on a cycle-by-cycle basis is known as cycle-accurate simulator, whereas instruction set simulator only models the execution of a program on a microprocessor through the eyes of an instruction scheduler along with a coarse timing of instruction execution. Most ...
AMD was the first to introduce the instructions that now form Intel's BMI1 as part of its ABM (Advanced Bit Manipulation) instruction set, then later added support for Intel's new BMI2 instructions. AMD today advertises the availability of these features via Intel's BMI1 and BMI2 cpuflags and instructs programmers to target them accordingly.
Cycle based simulator originally developed at DEC. The DEC developers spun off to form Quickturn Design Systems. Quickturn was later acquired by Cadence, who discontinued the product in 2005. Speedsim featured an innovative slotted bit-slice architecture that supported simulation of up to 32 tests in parallel. Super-FinSim: Fintronic: V2001
Instruction simulation is a methodology employed for one of several possible reasons: To simulate the instruction set architecture (ISA) of a future processor to allow software development and test to proceed without waiting for the development and production of the hardware to finish. This is often known as "shift-left" or "pre-silicon support ...
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.
Dymola - modeling and simulation software based on the Modelica language. DYNAMO - historically important language used for system dynamics modelling. Ecolego - a simulation software tool for creating dynamic models and performing deterministic and probabilistic simulations. EcosimPro - continuous and discrete modelling and simulation software.
OVPsim, a full-system simulation framework which is free for non-commercial use, and which comes with over 100 open source models and platforms that run Linux, Android, and many other operating systems. Qemu, open-source program that can do full-system simulation in the same way as Simics, including using hardware virtualization to accelerate ...
Initially MikroSim was developed to be a processor simulation software to be widely available in educational areas. Since MikroSim operability starts on the basis of microcode development, defined as a sequence of micro instructions (microcoding) for a virtual control unit, the software's intention is on first approach a microcode simulator with various levels of abstractions including the ...
