ultimo aggiornamento 12 gennaio 2014


 

Il programma EAGLE (ora alla versione 6.5.0) è un potente editor grafico per la progettazione di schemi e circuiti stampati: Comprende tre moduli: Schematic Editor, Layout Editor, Autorouter.
L'ultima versione del programma ha inserito la possibilità di importare/esportare gli schemi dal
programma LTSpice IV creato dalla Linear Tecnology.
LTSpice è un simulatore SPICE  (Simulation Program with Integrated Circuit Emphasis) freeware, è cioè un programma di simulazione circuitale che è stato sviluppato nel 1975 e oggi è distribuito sotto licenza BSD.
Nel corso degli anni è divenuto lo strumento standard per la simulazione di circuiti elettronici analogici.
Permette simulazioni in DC, AC, transitorio, DC sweep, e sul rumore.
Il motivo che è freeware, è dato dal fatto che contiene i modelli di dispositivi della Linear Technology e anche dei circuiti applicativi per questi dispositivi. Tuttavia è possibile scaricare i modelli di dispositivi di altre aziende e caricarli per le proprie simulazioni.

Sulla rivista n° 320 della rivista Fare Elettronica in edicola nel mese di Febbraio 2012, è stato pubblicato un mio 'articolo "Guida al programma Eagle" inerente il programma per il disegno di circuiti elettrici e circuiti stampati EAGLE

 

Schematic Editor

Layout Editor,

Autorouter

 

* Control Panel:
- Added a search bar for searches within the control panel tree.
Searches can be started via the context menu of a folder or the pulldown menu.
- Display of attributes in the preview for devicesets.

* User Language:
- New ULP constants EAGLE_PATH, EAGLE_DIR, EAGLE_HOME and OS_SIGNATURE.
- Added the members alwaysvectorfont and verticaltext to UL_BOARD and UL_SCHEMATIC.
- Added the member UL_TEXT.linedistance.
- Added new members dtype, extlength, extoffset and extwidth for UL_DIMENSION
(see DIMENSION section).
* Import/Export:
- Integration of the export of schematic and/or board libraries into EAGLE GUI.
Now available in File menu under Export/Libraries (a new ULP exp-lbrs.ulp
is used which replaces the existing exp-project-lbr.ulp).
- New import-accel.ulp for import of drawings in ACCEL ASCII format. This format
can be exported from P-CAD, Altium and Protel to import drawings into EAGLE.
- Under File/Import there are now sub entries for EAGLE drawing (the existing
"Paste from file" functionality) and the new ACCEL ASCII import.
- Now dimension objects are handled in the dxf.ulp.
- A number of further entries have been provided in 'File/Import' and 'File/Export'
which are handled by existing ULPs. Examples: Export of DXF (dxf.ulp), BOM
(bom.ulp), Hyperlynx (hyperlynx.ulp), import of bitmaps (import-bmp.ulp).
* ADD command:
- The ADD dialog now has a checkbox that allows to include/exclude packages
with pads in the search.
- The ADD dialog of the schematic editor now additionally displays attributes.
There is also a field for searches within attributes.
* LTSpice connection on Windows:
- Import of LTSpice schematics into EAGLE and export to LTSpice.
- LTSpice is a schematic simulation tool for free and available on Windows.
If installed, a simulation for an existing EAGLE schematic with automatic
conversion can be started from EAGLE.
- Possibility to create EAGLE devices from LTSpice library data through import
of according packages in PADS format, LTSpice symbols and connect lists.
* DIMENSION command:
- The general settings for dimension objects have been replaced by individual
properties for each dimension. This includes text size, ratio, unit, precision,
line width and extension line properties. The properties can be changed by
CHANGE DUNIT and CHANGE DLINE. That's also available in the CHANGE menu.
Text properties can be adjusted like for any other text.
For simplification some parameters like arrow length or text offset
are no longer offered and internal defaults used.
* Miscellaneous:
- Now the origins of elements are printed again if their layer is active.
- If a bus name has a synonym prefix, only that one will be displayed to avoid
too long labels.
- Support UNDO/REDO for approval/disapproval of ERC and DRC errors.
- A number of entries have been added to 'Tools' menu in schematic and layout
editor. These tools are handled by existing ULPs.
Examples: Mill outlines (mill-outlines.ulp), drill legend (drillegend-stack.ulp),
statistics (statistic-brd.ulp, statistic-sch.ulp).
* General GUI improvements:
- Added and adjusted wording, tool tips and status tips of pulldown menus and
all toolbars.
- Taken out "Paste from..." from Edit menu in schematic and board editor.
The identical functionality is available under File/Import.
- New options "Open Symbol", "Open Package" and "Open Device" available from
context menu for part instances and elements to open the related library
entities from schematic or board.
- Provided a bigger set of default key assignments for frequently used commands
by extending eagle.scr. The set of internally hardcoded function keys has been
reduced.
* Bugfixes:
- Now the text in the CHANGE TEXT dialog is initially selected again.
- Fixed DRC clearance calculation for polygons with same rank.
- Avoiding loss of precision when saving very small grid values.
- Corrected check for too small grid entries from user.
- Fixed handling of multiline text objects in polygon calculation.
- Fix for erroneous ERC warnings in relation to parts of devices
with predefined value (attribute 'VALUE').
- Correction in online help: VALUE command only available in default assembly variant.
- CHANGE PACKAGE/TECHNOLOGY: Ensure update of library attributes if they are displayed
but haven't been changed in schematic or board.
- Fixed a crash if a part is replaced by a device without package.
- Fixed handling of arbitrary pad shapes in the DRC.
- Avoided a crash if mixing the selection within nearby objects and textual input.
- Fixed a crash when doing a GATESWAP with an uninvoked gate.
- Fixed potential crash on MAC related to switching between editor windows, text window
or CAM processor window.
- Fixed graphic issues on MAC (display of popup menus).
- Fixed handling of dimensions in XML regarding extlength and extoffset.
- Fixed a crash in PRINT command on Windows if a previously used network printer is
uninstalled and EAGLE restarted.
- Fixed f/b annotation of attributes when copying parts in the schematic.
- Fixed displaying the pad names in the device preview of the ADD dialog.

Può essere usato sia in Windows 95/98/ME, Windows NT4/2000/XP sia in Linux basato sul kernel 2.x.    Occorre una risoluzione video grafica minima di 1024 x 768 pixels. Eagle esiste in più versioni. Si riportano alcuni dati essenziali delle versioni.

 

Versione Professional

Versione Standard

Versione Light Edition (Freeware)

Disponibile come Freeware (per testing e valutazione):

Sono comunque prodotti i file per la produzione (gerber e forature), possono essere visti e stampati progetti più grandi.
Quando si installa la versione Freeware non serve un User License Certificate.      Si sceglie l’opzione: Run as freeware.
Dopo l’installazione standard, EAGLE permette di personalizzare delle prestazioni, come la configurazione dei menù, i tasti funzione o i colori sullo schermo.
Si usa il menù Options o le varie finestre dell’editor.
