Description

 
Synopsis

Datatypes

data Signal (dom :: Domain) a Source #

Clash has synchronous Signals in the form of:

Signal (dom :: Domain) a

Where a is the type of the value of the Signal, for example Int or Bool, and dom is the clock- (and reset-) domain to which the memory elements manipulating these Signals belong.

The type-parameter, dom, is of the kind Domain - a simple string. That string refers to a single synthesis domain. A synthesis domain describes the behavior of certain aspects of memory elements in it.

  • NB: "Bad things"™ happen when you actually use a clock period of 0, so do not do that!
  • NB: You should be judicious using a clock with period of 1 as you can never create a clock that goes any faster!
  • NB: For the best compatibility make sure your period is divisible by 2, because some VHDL simulators don't support fractions of picoseconds.
  • NB: Whether System has good defaults depends on your target platform. Check out IntelSystem and XilinxSystem too!

Signals have the type role

>>> :i Signal
type role Signal nominal representational
...

as it is safe to coerce the underlying value of a signal, but not safe to coerce a signal between different synthesis domains.

See the module documentation of Clash.Signal for more information about domains.

Constructors

a :- (Signal dom a) infixr 5

Default domains

type System = "System" :: Domain Source #

A clock (and reset) dom with clocks running at 100 MHz. Memory elements respond to the rising edge of the clock, and asynchronously to changes in reset signals. It has defined initial values, and active-high resets.

See module documentation of Clash.Explicit.Signal for more information on how to create custom synthesis domains.

type XilinxSystem = "XilinxSystem" :: Domain Source #

A clock (and reset) dom with clocks running at 100 MHz. Memory elements respond to the rising edge of the clock, and synchronously to changes in reset signals. It has defined initial values, and active-high resets.

See module documentation of Clash.Explicit.Signal for more information on how to create custom synthesis domains.

type IntelSystem = "IntelSystem" :: Domain Source #

A clock (and reset) dom with clocks running at 100 MHz. Memory elements respond to the rising edge of the clock, and asynchronously to changes in reset signals. It has defined initial values, and active-high resets.

See module documentation of Clash.Explicit.Signal for more information on how to create custom synthesis domains.

vSystem :: VDomainConfiguration Source #

Convenience value to allow easy "subclassing" of System domain. Should be used in combination with createDomain. For example, if you just want to change the period but leave all other settings in tact use:

createDomain vSystem{vName="System10", vPeriod=10}

vIntelSystem :: VDomainConfiguration Source #

Convenience value to allow easy "subclassing" of IntelSystem domain. Should be used in combination with createDomain. For example, if you just want to change the period but leave all other settings in tact use:

createDomain vIntelSystem{vName="Intel10", vPeriod=10}

vXilinxSystem :: VDomainConfiguration Source #

Convenience value to allow easy "subclassing" of XilinxSystem domain. Should be used in combination with createDomain. For example, if you just want to change the period but leave all other settings in tact use:

createDomain vXilinxSystem{vName="Xilinx10", vPeriod=10}

Domain utilities

data VDomainConfiguration Source #

Same as SDomainConfiguration but allows for easy updates through record update syntax. Should be used in combination with vDomain and createDomain. Example:

createDomain (knownVDomain @System){vName="System10", vPeriod=10}

This duplicates the settings in the System domain, replaces the name and period, and creates an instance for it. As most users often want to update the system domain, a shortcut is available in the form:

createDomain vSystem{vName="System10", vPeriod=10}

vDomain :: SDomainConfiguration dom conf -> VDomainConfiguration Source #

Convert SDomainConfiguration to VDomainConfiguration. Should be used in combination with createDomain only.

createDomain :: VDomainConfiguration -> Q [Dec] Source #

Convenience method to express new domains in terms of others.

createDomain (knownVDomain @System){vName="System10", vPeriod=10}

This duplicates the settings in the System domain, replaces the name and period, and creates an instance for it. As most users often want to update the system domain, a shortcut is available in the form:

createDomain vSystem{vName="System10", vPeriod=10}

The function will create two extra identifiers. The first:

type System10 = ..

You can use that as the dom to Clocks/Resets/Enables/Signals. For example: Signal System10 Int. Additionally, it will create a VDomainConfiguration that you can use in later calls to createDomain:

vSystem10 = knownVDomain @System10

It will also make System10 an instance of KnownDomain.

If either identifier is already in scope it will not be generated a second time. Note: This can be useful for example when documenting a new domain:

-- | Here is some documentation for CustomDomain
type CustomDomain = ("CustomDomain" :: Domain)

-- | Here is some documentation for vCustomDomain
createDomain vSystem{vName="CustomDomain"}

Traversable

traverse# :: Applicative f => (a -> f b) -> Signal dom a -> f (Signal dom b) Source #

EXTREMELY EXPERIMENTAL

joinSignal# :: Signal dom (Signal dom a) -> Signal dom a Source #

WARNING: EXTREMELY EXPERIMENTAL

The circuit semantics of this operation are unclear and/or non-existent. There is a good reason there is no Monad instance for Signal.

Is currently treated as id by the Clash compiler.
