Speedgoat IO33x-06 Interface
Speedgoat IO33x-06 Interface — Front interface with 16 differential analog inputs, 8 analog outputs
and 16 digital inputs/outputs
Supported Modules
IO332-200k
IO333-325k, IO333-410k
Reference Design Parameters
Be sure to select "-06" as your reference design's front plugin using the pulldown
menu at step 1.2 of the workflow advisor so that the appropriate interfaces will be
available in step 1.3 of the workflow.
GPIO Interface
IO33x-06 GPIO Channel [0:15]
The IO33x-06 I/O module provides 16 General Purpose TTL I/O lines. All I/O lines
are implemented with a 5 V pull-up resistor.
Data Type: boolean
Direction: input/output
Analog Input Interface
IO33x-06 AI Data [0:15]
The IO33x-06 I/O module provides 16 simultaneous 16-bit 500 kHz analog input
channels with an analog input range of ±10.24 V, ±5.12 V, ±2.56 V or ±1.28 V. The
corresponding IO33x-06 AI Trigger [0:15] and IO33x-06 AI Valid
[0:15] must be selected as well.
16 channels
Data Type: int16
Direction: input
IO33x-06 AI Valid[0:15]
This mandatory port indicates when the analog input data
is valid. The port signal is a single clock pulse of the design under test (DUT)
frequency. Since the DUT can be set to run faster than the ADC, there will not
necessarily be valid data available at every clock tick.
IO33x-06 AI Trigger [0:15]
This mandatory port triggers the conversion of the
analog input. Ideally the trigger signal should be implemented as a single clock
pulse of the design under test (DUT) frequency.
Analog Output Interface
IO33x-06 AO Data [0:7]
The IO33x-06 I/O module provides eight 16-bit analog output channels with
simultaneous updates for every four channels at a maximum rate of 100 kHz (10 µs
settling time). The corresponding IO333x-06 AO Trigger [0:1] must be
selected as well.
7 channels
Data Type: int16
Direction: output
IO33x-06 AO Trigger [0:1]
This mandatory port triggers the analog outputs.
Ideally the trigger signal should be implemented as a single clock pulse of the
design under test (DUT) frequency.
IO33x-06 AO Ready [0:1]
This non-mandatory port indicates to the design under
test (DUT) that the analog output conversion has completed. When the conversion
completes, this signal will go high, to indicate to the DUT that a new data value
can be passed to the analog output.
