Document Table of Contents Accessing the Voltage Sensor Using FPGA Core Access

In user mode, you can implement a soft IP to access the voltage sensor block. To access the voltage sensor block from the core fabric, include the following WYSIWYG atom in your Intel® Quartus® Prime project:

WYSIWYG Atom to Access the Voltage Sensor Block

	.clk (<input>, clock signal from core),
	.reset(<input>, reset signal from core),
	.corectl(<input>, core enable signal from core),
	.coreconfig(<input>, config signal from core),
	.confin(<input>, config data signal from core),
	.chsel(<input>, 4 bits channel selection signal from core),
	.eoc(<output>, end of conversion signal from vsblock),
	.eos(<output>, end of sequence signal from vsblock),
	.dataout(<output>, 12 bits data out of vsblock)
Table 124.  Description for the Voltage Sensor Block WYSIWYG
Port Name Type Description
clk Input Clock signal from the core. The voltage sensor supports up to an 11-MHz clock.
reset Input Active high reset signal. An asynchronous high-to-low transition on the reset signal starts voltage sensor conversion. All registers are cleared and the internal voltage sensor clock is gated off when the reset signal is high.
corectl Input Active high signal. "1" indicates the voltage sensor is enabled for core access. "0" indicates the voltage sensor is disabled for core access.
coreconfig Input Serial configuration signal. Active high.
confin Input Serial input data from the core to configure the configuration register. The configuration register for the core access mode is 8 bits wide. The LSB is the first bit shifted in.
chsel[3:0] Input 4-bit channel address. Specifies the channel to be converted.
eoc Output Indicates the end of the conversion. This signal is asserted after the conversion of each channel data packet.
eos Output Indicates the end of sequence. This signal is asserted for one cycle after the completion of the conversion of the selected sequence.
dataout[11:0] Output
  • dataout[11:6]—6-bit output data.
  • dataout[5:0]—Reserved.
