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.
To provide the boundary scan capability, IC vendors add additional logic to each of their devices, including scan cells for each of the external traces. These cells are then connected together to form the external boundary scan shift register (BSR), and combined with JTAG Test Access Port (TAP) controller support comprising four (or sometimes more) additional pins plus control circuitry.
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.
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 ...

While the code executes, the user can observe what is happening on the address, data, and control signals of the microprocessor. The MPT8080 acts like a simulator , in that code can be stepped through one instruction —or each cycle of each individual instruction—at a time to observe what is happening.
Algodoo - 2D physics simulator focused on the education market that is popular with younger users. Simcenter Amesim - a platform to analyze multi-domain, intelligent systems and predict and optimize multi-disciplinary performance. Developed by Siemens Digital Industries Software. ANSYS - engineering simulation.
GNUSim8085 is a graphical simulator, assembler and debugger for the Intel 8085 microprocessor in Linux and Windows. It is among the 20 winners of the FOSS India Awards announced in February 2008. [1] GNUSim8085 was originally written by Sridhar Ratnakumar in fall 2003 when he realized that no proper simulators existed for Linux.
