AI Technical Summary
Technical Problem
In analog-digital hybrid simulations, the voltage of a high-frequency PWL voltage source triggers digital changes when it rises to the low and high threshold voltages, causing the simulator to refuse to calculate results and severely slowing down the simulation speed.
Method used
Calculation breakpoints are inserted when the voltage source reaches the low threshold voltage and the high threshold voltage. The voltage value is calculated based on the calculation breakpoint and converted into a digital signal to avoid invalid calculations.
Benefits of technology
It improves simulation speed and efficiency, reduces unnecessary calculations, and improves simulation performance by approximately 40%.
