Description

DDR primitives for Intel FPGAs using ALTDDIO primitives.

For general information about DDR primitives see Clash.Explicit.DDR.

Note that a reset is only available on certain devices, see the ALTDDIO user guide for the specifics: https://www.altera.com/content/dam/altera-www/global/en_US/pdfs/literature/ug/ug_altddio.pdf

Synopsis

altddioIn :: forall deviceFamily a dom domDDR. HasCallStack => KnownDomain dom => KnownDomain domDDR => DomainPeriod dom ~ (2 * DomainPeriod domDDR) => DomainActiveEdge dom ~ 'Rising => BitPack a => SSymbol deviceFamily -> Clock dom -> Reset dom -> Enable dom -> Signal domDDR a -> Signal dom (a, a)
altddioOut :: forall deviceFamily a dom domDDR. HasCallStack => KnownDomain dom => KnownDomain domDDR => DomainPeriod dom ~ (2 * DomainPeriod domDDR) => DomainActiveEdge dom ~ 'Rising => BitPack a => SSymbol deviceFamily -> Clock dom -> Reset dom -> Enable dom -> Signal dom (a, a) -> Signal domDDR a

Documentation

altddioIn Source #

Arguments

:: forall deviceFamily a dom domDDR. HasCallStack
=> KnownDomain dom
=> KnownDomain domDDR
=> DomainPeriod dom ~ (2 * DomainPeriod domDDR)
=> DomainActiveEdge dom ~ 'Rising
=> BitPack a
=> SSymbol deviceFamily	The FPGA family For example this can be instantiated as follows: SSymbol @"Cyclone IV GX"
-> Clock dom
-> Reset dom
-> Enable dom
-> Signal domDDR a	DDR input signal
-> Signal dom (a, a)	Normal speed output pair `(o0, o1)`

Intel specific variant of ddrIn implemented using the ALTDDIO_IN IP core.

Reset values are 0

Of the output pair (o0, o1), o0 is the data clocked in on the falling edge and o1 is the data clocked in on the rising edge, and o0 comes before o1 in time.

NB: This primitive only supports rising edges as the active edge.

altddioOut Source #

Arguments

:: forall deviceFamily a dom domDDR. HasCallStack
=> KnownDomain dom
=> KnownDomain domDDR
=> DomainPeriod dom ~ (2 * DomainPeriod domDDR)
=> DomainActiveEdge dom ~ 'Rising
=> BitPack a
=> SSymbol deviceFamily	The FPGA family For example this can be instantiated as follows: SSymbol @"Cyclone IV E"
-> Clock dom
-> Reset dom
-> Enable dom
-> Signal dom (a, a)	Normal speed input pair `(i0, i1)`
-> Signal domDDR a	DDR output signal

Intel specific variant of ddrOut implemented using the ALTDDIO_OUT IP core.

Reset value is 0

Of the input pair (i0, i1), i0 is the data clocked out on the rising edge and i1 is the data clocked out on the falling edge, and i0 comes before i1 in time.

NB: This primitive only supports rising edges as the active edge.
