Struct MemoryReadPort

pub struct MemoryReadPort {
    pub addr: Value,
    pub data_len: usize,
    pub flip_flop: Option<MemoryReadFlipFlop>,
}

A memory read port, either synchronous or asynchronous.

Fields

addr: Value

The read address, selecting which row(s) to read. Follows the same rules as MemoryWritePort address.

Reading an out-of-bounds address results in an undefined value.

data_len: usize

The width of the read data. Must be a power-of-two multiple of the memory width.

flip_flop: Option<MemoryReadFlipFlop>

A flip-flop-like structure describing the synchronous read port, or None for asynchronous read ports. If this is None, the read port continuously reads the memory row(s) selected by the addr value and outputs that as the read data.

Implementations

impl MemoryReadPort

pub fn new_asynchronous(addr: impl Into<Value>, data_len: usize) -> Self

pub fn new_clocked( addr: impl Into<Value>, data_len: usize, clock: impl Into<ControlNet>, ) -> Self

pub fn wide_log2(&self, memory: &Memory) -> usize

pub fn visit(&self, f: impl FnMut(Net))

pub fn visit_mut(&mut self, f: impl FnMut(&mut Net))

Trait Implementations

impl Clone for MemoryReadPort

fn clone(&self) -> MemoryReadPort

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MemoryReadPort

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for MemoryReadPort

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MemoryReadPort

fn eq(&self, other: &MemoryReadPort) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
