To perform a full autoroute, choose 

Autoroute»Start/Resume 

Autorouter

Ultiboard begins routing your board and displays its progress in the status 
line. When the process is complete the results are displayed in the 

Results

 

tab of the 

Spreadsheet View

Interactivity

Ultiboard provides complete interactivity, letting you stop the routing 
process as desired to manually place items and then continue autorouting 
when ready. 

To stop autorouting, select 

Autoroute»Stop/Pause Autorouter

To restart, select 

Autoroute»Start Autoplacement

Autorouting buses

The circuit shown below is used in this example. Bus 1 consists of the five 
nets that connect the two ICs. 

 

Note

To autoroute buses, the topology for the nets, as set in the 

Net edit

 dialog box, must 

be set to either 

Daisy chain

 

or 

Star

 and the nets must be part of a 

Bus Group

 (in the 

Groups

 tab of the 

Net edit

 dialog box). Refer to th

Setting Group Parameters

 section of 

Chapter 5,
