# REQuest ⇄ ACKnowledge

JavaScript Tool set to construct, transform and analyze digital circuits based on elastic transactional [protocol](./docs/protocol.md) and Request-Acknowledge handshake.

User describes circuit JavaScript API, add standard components from the library, or create new componets.

Several standard [controllers](./docs/controller.md) provided.

User can transform constructed circuit by changing buffer capacity or performing other correct by construction transformations.

## Usage

The package can be installed from `npm`:

```sh

npm i reqack

```

and imported into your JavaScript code:

```js

const reqack = require('reqack');

```

A **circuit** can be constructed this way:

```js

const g = reqack.circuit('circuit_name');

```

A **node** can be constructed by calling the circuit function. Optional `node_label` string will be used as standard or custom operation or as a root of a signal name.

```js

const node1 = g('node_label');

```

A **edge** can be constructed by calling the node function. Optional argument is an `Object` with two major properties (width, capacity).

```js

const edge1 = node1({width: 32, capacity: 1});

```

One node can be **connected** to another node by calling edge with a destination node.

```js

edge1(node2); // -> edge1

```

Resulted Verilog RTL can be produced by calling

```js

const verilogString = reqack.verilog(g, {});

```

SVG image can be rendered by calling

```js

const svg = reqack.svg(g);

```

## Testing

```sh

npm i

npm test

```
