A system implement simulation system's capable of facilitating integrated circuit designers to perform a complete integrated circuit testing with respect to a target peripheral device and demonstrate various functions and their sequence of operations without having to build the target device physically. The system allows, reliability and quality of an integrated circuit design to be increased, and production and testing costs can be reduced. The simulation system is capable of performing functional checking at any time, and can be utilized in demonstrating product functions to customer.
Device emulation implemented in programmable circuits. In one aspect, an interface for providing control of a hardware device includes functional code embedded in circuitry of the interface. Emulator code is embedded in programmable circuitry of the interface to emulate the hardware device during testing of the functional code and the interface. Another aspect diagnoses errors in a system having an interface and a connected hardware device, using emulator code embedded in a programmable circuit of the interface.
A method for system simulation, which is distinguished by a first sequence of steps for simulating a microcontroller/microprocessor and peripheral modules using predetermined signal patterns and by a second sequence of steps for interrogating and evaluating system states that are brought about by the simulation. In order to carry out the second sequence, the first sequence is interrupted as dictated by markers that have been inserted into the first sequence, and the second sequence is executed in an accelerated operational mode that has been adapted to the evaluation.
Exemplary methods, apparatuses, and products are described for creating a behavioral model of a hardware device for use in a simulation environment. The behavioral model is created by an iterative process that includes receiving in a simulated hardware device from a simulated device under test (`DUT`) a stimulus waveform. The stimulus waveform includes data representing a number of stimuli. In response to receiving the stimulus waveform, the simulated hardware device presents a recorded response waveform from a recorded response file to the DUT. The stimulus waveform is also recorded. The recorded stimulus waveform is presented to the hardware device. A response waveform that results from presenting the recorded stimulus waveform to the hardware device is recorded in the recorded response file.
A system and method is described for connecting a logic circuit simulation to a hardware peripheral that includes a computer running software for communicating data to and from the hardware peripheral. The software transmits the data received from the hardware peripheral to the device being simulated by the logic circuit simulation. The computer also transmits the data received from the device being simulated by the electronic circuit simulation to the hardware peripheral. This allows the user to test the device being simulated using real hardware for input and output instead of simulated hardware.
