Preface

TARGET 3001! contains two internal autorouters, the contour router and the hybrid router. From TARGET-Version V15 an additional 250 Pin demo-version of the powerful external autorouter ELECTRA is delivered with every TARGET 3001! - edition. You can create real production data within its 250 pin limit. Full ELECTRA versions can separately be purchased, prices see below. ELECTRA is suitable for the more advanced and complex projects. It is working very quickly and reaches high completion rates. ELECTRA is a product of Konekt SPRL, Belgium, www.konekt.com

Specify min/max length amplitude for serpentine pattern (PCB/Class/Net levels)
Control for serpentine length gap
"Report network" function to show length stat details of selected nets
Differential pair autorouter to support pre-fanout
Fanout in zigzag pattern
Tune command to autoadjust in-place routed matched/min length nets
Enable/disable diff pairs routing to route as single nets
Protect/unportect command to protect diff pairs only

Improved net length reporting

ELECTRA V5

New in ELECTRA V5:

Fast Pattern Router producing in everage 20% less total vias
enhanced Mitering for long 45° diagonal
New 250 Pin Demo version Same link as above.

(Dec. '16)
Note: ELECTRA routs significantly quicker, if you waive the use of octagonal pads. Better use round or rectangular ones.

  - Especially useful around BGAs and fine SMDs
  - Interactive region editor to define area, width and clearance
Router Strategy Dialog
New Graphical User Interface
Report of routing via styles
Improved layout display
- Polygon outline and blind/buried via display
Reset and restart - Try different routing strategies with a reset command that deletes all routing
Simplified and robust licensing
- For node-locked licenses, Site and MID codes are now unaffected by changes to BIOS, MB and OS
- One step configuration upgrade
- Hassle-free floating license setup
Improved User Guide with Tech Tips section

How much is an ELECTRA license?

All configurations support unlimited power and ground layers. For instance, Route 2L supports two signal layers plus unlimited power and ground layers. All configurations include advanced rule support and mitering capability. Pricing is for node-locked licenses on Windows operating system.

License

Please note that a purchased Electra licence is fixed to one certain computer (node locked licene) while an activation code is required. Please ask for this activation code by transmission of the Machine Identity Code (MID) as well as the Site Code to IBF.please press the caps lock key and click on the electra.exe of the 15 days trial edition (not the 250 Pin demo edition.) In case of a computer exchange the license can migrate as well, please see below.

Further information: Konekt.com or see the ELECTRA user guide.

How to migrate ELECTRA to a new PC

Prior to launching ELECTRA you should activate the CapsLock key, this will force the startup license dialog to show up when clicking the electra.exe. In order to transfer a node-locked license from one computer to another, tick the radio button "Transfer license" and press "Continue>>". You also have to enter the original activation code for security reasons (this will prevent accidental or unauthorized license transfer). The license transfer now is managed in four steps:

*Initial situation: Unlocked application is located on source computer A (already unlocked with activation code A) and the client wants to transfer his license to target computer B.

Step 1: The user should install and run ELECTRA on target computer B.
Step 2: ELECTRA on target computer (B) will display activation dialog box with "Site code B" which is different from "Site code A". "Activation code B" will be required for program unlocking.
Step 3: The user should run unlocked application (computer A), set "Activation code" field to previously issued "Activation code A" (which was initially used for program unlocking on computer A), set "New Site code" field to "Site code B" and press "Continue >>" button.
Step 4: Protected ELECTRA will display dialog box with "Activation code B" which she/he should use to unlock the protected application on computer B.
Resulting situation: License will be removed from computer A and transferred to computer B.

ELECTRA Update

Remark: An Update within ELECTRA V2 or ELECTRA V4 is free of charge. An update from V2 to V4 is a purchase.

You can easily update your purchased version V4 of ELECTRA by exchanging the electra.exe file. Its location please find according to the path shown in the image above (see chapter 3: "Try it for free").

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 your destination 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.
