Why is IRQ not automatically cleared to 0 in single cycle conversion mode when simulating the MAX 10 ADC IP Core?

Environment

  • Intel® Quartus® Prime Pro Edition
  • Modular ADC core Intel® FPGA IP
  • Simulation, Debug and Verification
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    The EOP bit in the ISR register of the Modular ADC IP Core in MAX® 10 devices, which is responsible for generation of IRQ, is set to ‘1’ by hardware when a complete block of samples is received. This bit does not automatically clear to 0 in RTL simulation. Users need to write 1 to this bit in order to clear it.

    Resolution

    To clear this EOP bit to 0 for the next interrupt, write 1 to ISR register to indicate that a complete block of samples is received.
