Hardware Targets for DSP

Shift in one step from simulation to MCU code

Spend your time on what matters most to your design.

With time pressures and the need for trusted results, PSIM’s Hardware Targets let you test and troubleshoot control algorithms and generate ready-to-run C code automatically. The DSP Oscilloscope gives you real-time control and waveform display.

Write fixed-point DSP code.

With total ease-of-use driven by an intuitive interface, the Target modules let you run efficient simulations and get reliable and fast results. Test and troubleshoot control algorithms, generate ready-to-run C code automatically, and take advantage of real-time control and waveform display with the DSP Oscilloscope. Use the target modules to automatically check variables for overflow – no more manual checks.

Ready-to-run code

With SimCoder and either of the supported Target Modules, debug and validate a control algorithm thoroughly in PSIM, and from the control schematic, generate ready-to-run C code automatically for Texas Instruments’ F2802x, F2803x, and F2806x series fixed-point DSP or for their F2833x, F2837x, and F28004x series floating-point MCU. IQmath resolution can be checked for overflow automatically through simulation instead of manual trial and error.

The target modules will allow you to spend your time testing and troubleshooting control algorithms and hardware instead of studying datasheets to determine things like which bits in a register need to be set so that your ADC is triggered at the beginning of a PWM duty cycle.

The generated code will work with any DSP hardware board as long as the board uses the correct series DSP for the hardware target used.

Texas Instruments InstaSPIN is now fully supported in PSIM, both in simulation only and in SimCoder with code generation. For more details on this exciting new PIL feature, review our PSIM Instaspin page.

Target Library, Scaling and Overflow Check

Target Library

The hardware target libraries include elements for the following DSP functions:

A/D converter
Digital inputs and outputs
PWM generator
Encoder and counter
SCI interface
SPI interface
Interrupts including trip-zone, comparator, and capture
Clock frequency selection

DSP Oscilloscope

Easily test, debug, and modify the DSP code in a non-disruptive and non-intrusive way.

Based on the targets’ SCI interface, PSIM provides the DSP Oscilloscope function that can display the real-time waveforms of the variables inside the DSP. The DSP Oscilloscope also provides the capability to modify the value of DSP runtime variables during real-time system operation of the physical hardware.

DSP Oscilloscope and C-Code Generation

Use the DSP oscilloscope to identify internal process variables of the DSP to be monitored in the PSIM schematic. When the control schematic is translated into c-code using PSIM, the necessary code will be automatically setup so that these variables can be monitored using the DSP Oscilloscope interface in real-time.

Simply select and trigger the signals as you would in a standard oscilloscope.
