16.36. Memory - Data latch
Description
Data latch simulates a data latch. Similar to D flip-flop, but supports integers for input
(D flip-flop uses logical signals only)
Inputs
Data in (32-bit integer): Integer data input
CLK (Logic): Clock input signal
Outputs
Value (32-bit integer): Stored integer data
Value F (32-bit integer): Stored integer data (on falling edge) in bi-directional mode
Properties
Default value (Integer): Default reset value
Bi-directional (Logic): If True, the latch samples on both the rising edge and falling
edge.
Retain on reset (Logic): If True, the value is saved to battery-backed RAM. Also
disables default value setting.
Initial value (Integer): The initial value of the retained block after it gets uploaded to
the device.
Remarks
None
16.37. Memory - 1 T delay
Description
1 T delay simulates a one-cycle delay
Inputs
In (32-bit integer): Integer data input
Outputs
Q (32-bit integer): Integer data output
Properties
Default value (Integer): Default reset value
Remarks
None
16.38. Memory - MIN memory
Description
MIN memory remembers the minimum value of the Data in signal. Use CLK input to
reset the memory.
Inputs
Data in (32-bit integer): Integer data input
CLK (Logic): Clock input signal
Outputs
Value (32-bit integer): Stored minimum value
Properties
Default value (Integer): Default reset value
Retain on reset (Logic): If True, the value is saved to battery-backed RAM. Also
disabled default value setting.
Initial value (Integer): The initial value of the retained block after it gets uploaded to
the device.
Remarks
None
