# Simulate a Workflow

## **Setup Requirements**

* **Set up Inverter Network SDK**: Refer to the[ Quick Start](https://docs.inverter.network/sdk/typescript-sdk) guide for detailed instructions.

As we support multicall functionality there is a case for simulating a workflow deployment which enables us to retreive certain addresses before they exist.

{% hint style="info" %}
*( optional )* You can pass in a ModuleData typed object into the `requestedModules` constant's fields, this makes it so that you can work with your self managed inverter modules
{% endhint %}

```typescript
// EXEMPLE MixedRequestedModules USAGE
import type { ModuleData, MixedRequestedModules } from '@inverter-network/sdk'

const AUT_Roles_v1 = {'<your_module_data>'} as const satisifies ModuleData

const requestedModules = {
    fundingManager: 'FM_DepositVault_v1',
    paymentProcessor: 'PP_Simple_v1',
    authorizer: AUT_Roles_v1,
} as const satisfies MixedRequestedModules
```

## Simulating the Workflow Deployment

**Parameters**

* **`requestedModules` (required)**:\
  This parameter defines the modules which will be simulated.
* `args` **(required)**:\
  This parameter is used to tell the simulations what the modules arguments are.
* `tagConfig` **(optional)**:\
  This parameter is to tell the arg's parser how to parse the arguments.
* `useTags` **(optional):**\
  This parameter is to optionally disable auto format parse for inputs and outputs (default true).
