5.1. Modular ADC Core Parameters Settings

There are three groups of options: General, Channels, and Sequencer.
Table 16.   Modular ADC Core Parameters - General
Parameter Allowed Values Description
Core Variant
  • Standard sequencer with Avalon-MM sample storage
  • Standard sequencer with Avalon-MM sample storage and threshold violation detection
  • Standard sequencer with external sample storage
  • ADC control core only

Selects the core configuration for the Modular ADC Core IP core.

Debug Path
  • Disabled
  • Enabled

Enables the debug path.
Generate IP for which ADCs of this device?
  • 1st ADC
  • 2nd ADC

For devices that have two ADC blocks, specifies which ADC block you want to instantiate using the IP core.

ADC Sample Rate 25 kHz, 50 kHz, 100 kHz, 200 kHz, 250 kHz, 500 kHz, and 1 MHz

Specifies the ADC sampling rate. The sampling rate you select affects which ADC input clock frequencies are available.

Refer to the related information for more details about the sampling rate and the required settling time.

ADC Input Clock 2 MHz, 10 MHz, 20 MHz, 40 MHz, and 80 MHz

Specifies the frequency of the PLL clock counter zero (c0) clock supply for the ADC core clock.

  • You must configure the c0 of the first ALTPLL IP core that you instantiate to output one of the frequencies in the allowed values list.
  • Connect the ALTPLL c0 output signal to the Modular ADC Core clk_in_pll_c0 input signal.

For valid ADC sampling rate and input clock frequencies combinations, refer to the related information.

Reference Voltage Source
  • External
  • Internal

Specifies the source of voltage reference for the ADC:

  • External—uses ADC_VREF pin as the voltage reference source.
  • Internal—uses the on-chip 2.5 V (3.0/3.3V on voltage-regulated devices) as the voltage reference source.
External Reference Voltage
  • Dual supply devices: up to 2.5 V
  • Single supply devices: up to 3.63 V

Specifies the voltage of ADC_VREF pin if you use it as reference voltage to the ADC.

Enable user created expected output file
  • Enabled
  • Disabled
 Specifies the source of output data for ADC logic simulation:
  • Enabled—uses the stimulus input file you provide for each ADC channel, except the TSD channel, to simulate the output data.
  • Disabled—uses fixed expected output data for all ADC channels. This is the default setting.

For more information about user-specified ADC logic simulation output, refer to the related information.

Table 17.   Modular ADC Core Parameters - Channels This group of parameters is divided into several tabs—one for each channel, and one tab for the TSD.
Parameter Allowed Values Description
