Hi!
I'm a total newbie at this.
I have three programs recently installed.
These are PADS Logic (where I've managed to draw a simple test schematic), PADS Layout (where I've managed to place the components in what I think is a double-sided PCB) and PADS Router (where I've managed to manually route some of the connections).
Everything works fine until I try autorouting or even manually routing some of the connections.
I understand that these connections cannot be routed "across" the other connections (i.e I get a clearance warning).
But how do I tell the router to use the other side?
And why does not the (auto)router understand this?
I obviously have some settings wrong.
But there are so many of them
Best regrads, Roger
PS
Where and how do I set the actual size of the PCB? I want to use EU-sizes only.
I am sure the tutorials will answer the question eventually. However, if the problem is what I suspect, there is a quick answer. It is to do with the layer setup and routing rules.
This can be done in either the schematic prior to making the netlist, or in the PCB layout. First check your layer setup. (setup>layer definition). For a multilayer board it should look something like 1.jpg.
Next, select the layers you want to route on (setup>design rules>default>routing). I suspect it will look something like 2.jpg. Select the layers and add. It should now look like 3.jpg. The board should now route.
Board size. If it is just a rectangle, create the rectangle and the right click select board outline and double click one side of the board and manually enter the dimensions. Do this for the opposite side and you have your board size. I usually save standard sized boards as blank PCB's (make them read only!) and import my netlists into them then save straight away.
