How to migrate ELECTRA to a new PC

The most recent best practise you'll find on the Electra page: See the ELECTRA pricing site at "Licensing information" where the "How to Transfer your License" - link is:
http://konekt.com/wp/pricing/

1. Install the ELECTRA download to the new PC "B" and note the new Site Code to a piece of paper.
2. Go back to old PC "A", hold the "shift key" while launching ELECTRA, the old license dialog shows up.
3. Select "Transfer license" and enter the Site Code of new PC "B" to the field to the right.

Electra license dialog

4. Hit Continue>> so that the new activation code will be generated.

New Activation Code

Image: New Activation Code

5. Save the new activation code as a small text file on any medium (e.g. USB stick) in order to carry it to computer B. You might also send it in an email to yourself to the new computer (to transfer it properly. Or maybe use your smartphone...
6. Enter the new activation code to the field "Activation code" on the new PC.Done.

If a transfer from the old computer is no longer possible, e.g. after a computer crash, then you must request a new activation from us. If you own the current Electra version or even one year after purchase, this service is free of charge once. Otherwise you have to pay to update to the latest version of Electra to get new codes. These are the service rules of the manufacturer of the Electra router, we have no influence on it.

ELECTRA Update

An Update within the current main ELECTRA version number is free of charge. An upgrade from lower editions or earlier main versions is a purchase.

You can easily update your purchased current version of ELECTRA by exchanging the electra.exe file. This is how you get it:

Electra Update

Image ELECTRA Update. Link to the ELECTRA website: https://konekt.com/

Save the setup.exe provided by the link to a directory of your choice. A double click upon it later opens the install shield. During the setup you will get asked where to install the electra.exe. Now choose the same destination (the same path) so that TARGET 3001! later will be able to find the new exe-file.

How does ELECTRA produce a PCB layout from my TARGET 3001! schematic?

After your schematic work in TARGET has finished, you would import your packages to the layout. Now you see a tangle of air wires (ratsnest), which now wait for disentangeling. ELECTRA asks TARGET 3001! to create a file in the DSN standard, which ELECTRA is able ro read in. The routing result which ELECTRA delivers is a session file (*.ses), which TARGET now is able to read in (see image to the left). This happens for TARGET users on button click. No bustling around in TARGET itself.

An example:

Image: A TARGET project unrouted. Then [Ctrl]+[R] pressed to open the dialog "External Autorouter".


No signal highlighted means: All signals will be used for routing. After pressing "Start" ELECTRA overtakes a *.dsn file and routs it. After ELECTRA has done its work it simply needs to be saved, so that instantly a session file (*.ses) will be made out of it. The image of the routing result in ELECTRA can be closed:

Image: Save the *.dsn file and so create the *.ses file.

Image: Accept the proposed saving directory and press "Save".

Image: Accepts the routed project to TARGET by saying "Yes".

Image: The routed project in TARGET 3001!. All tracks can now be manupulated as usually in TARGET.

What do the tabs of the dialog for external auto routers in TARGET 3001! mean?

In Tab "Signals" all unrouted signals appear in a list. Which signal you'dlike to have routed please select by highlighting its signal name in the list. Using the [Ctrl] key you can highlight several signals at the same time. Clicking it again will unhighlight it. With the buttons "Select all", "Deselect all", you'll have them on one strike. If you press "Start", without having highlighted any signal, all signals get routed.

Image: The "Signals" tab in the External autorouter dialog

In section "Signal tracks" you can enter to the line "Minimum Track width:". This value is taken at minimum while routing even if you define it smaller in the schematic signal. But if you define a bigger value in the schematic signal than the one entered here, the bigger one will be taken. The same with the minimum spacing of tracks. At first the distance copper to copper counts. In the project test dialog the aura can be added. Vias also can achieve minimum width values regarding the drill hole. The width of an annular copper ring around the drill hole can be defined. An annular ring exists if a 4mm copper circle is center drilled by a 2mm drill. Around the hole a ring of 1mm width remains. The minimum entries here control the size of the vias.

The tab "Algorithm" allows strategic settings. Memory structures (as far as used in the layout) might be routed first in order not to have too many obstacles later. The same with fan outs at packages having a narrow pinout. Fan outs allow an escape to the opposite layer with a differently preferred routing direction. During disentangeling passes connections are made, during optimization passes the track lengthes are tightened.

Image: Tab "Algorithm" in the External autorouter dialog

Set the path to the electra exe You can tell TARTET 3001! where the electra exe is located. Enter the path to the line: "External Router, program-file" so that TARGET 3001! will start it.

In tab "Route layers" please select a certain routing layer and in the area to the right define how the layer shall be used for which signals. Preferred routing direction means the preferred direction of the tracks on one layer face: horizontally or vertically.

Image: Tab "Route layers" in the External autorouter dialog

Good if for every layer a certain preferred routing direction is defined. Routing in all directions upon one layer can be avoided that way. At the same time one can predefine certain layers for certain signals or forbid them for certain signals. A Route prohibition area is defined on a certain layer having exactly this function.
