Struct Ram 

pub struct Ram {
    pub name: String,
    pub kind: String,
    pub ports: Vec<(u64, u64)>,
    pub byte: Option<u64>,
    pub old_data: bool,
}

A memory as synthesis left it: its path, the block it asked for (AUTO, M20K block, MLAB), each port’s depth and width, its byte enables’ byte when it has them, and whether a read on one port during a write on the other must give the old data.

Fields

name: String

kind: String

ports: Vec<(u64, u64)>

byte: Option<u64>

old_data: bool

Implementations

impl Ram

pub fn m20k(&self) -> u64

The M20K blocks the fitter gives the memory: none for one asked into MLABs, none for an AUTO one the fitter turns into MLABs, and otherwise its costlier port’s blocks (m20k_blocks, byte-enabled lanes holding a byte each). The fitter turns an AUTO memory into MLABs when it is small (every port 32 words of at most 42 bits, 64 of at most 10, or 128 of at most 5, as hybrid7b’s fit did) and needs no old data across its ports, which an MLAB cannot give.

Trait Implementations

impl Clone for Ram

fn clone(&self) -> Ram

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ram

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

Formats the value using the given formatter.

impl PartialEq for Ram

fn eq(&self, other: &Ram) -> 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.
