Microcontroller H8S2128 Offpage connector Design pages Overview VCC (+5v) GND (0v) Library of symbols
4
Place a part Place Part in the Libraries field, select Sulautetut2, in the Part List field, select DB9S, then Click OK. To rotate a part : Select a part (left click on the part), CTRL-R. Place a wire Place Wire, Use the mouse to draw the wire. Place an offpage connector to connect 2 pins that are on different design pages, ! Give the same name on each of the pages, for one connection. e.g a DB9 connector (for serial communication)
5
Toolbar for wires, parts, GND, VCC, offpage connectors...
6
Design Rule check : unconnected nets, off-page connectors Tools Design Rule Check Nota: menu Tools is visible only when a design page is selected.
7
Create a netlist (.MNL) Tools Create Netlist Check the report messages in the Session Log window. Automatic update Capture Layout
8
Layout Pad : Copper (kupari) Copper Insulation (eristys) Hole (reikä) if copper on the interior of this cylinder : pad is also via Top layer Bottom layer Bottom/Top layer view Footprint : padstack(s) + obstacle(s) Padstack : list of those dimensions for one pad. (the current flows between layers).
9
Start Cadence PSD 14.0 Layout File New Default.tch / Metric.tch (inches/mm). then automatically, Layout asks the netlist file (.MNL), next the name of the main output file (.MAX) next the footprints of the components..../... Use the library EVALBOARD.LLB for the main components; some footprints are missing, like the crystal resonator (Take e.g., a capa footprint. The crystal is not needed when using the emulator).

System settings : units Options System Settings
12
Spacing between items: used as routing rules. Options Global Spacing
13
Layers : 3 layers of interest Tools Layers Select from Spreadsheet
14
Nets selections/settings : Tools Nets Select from Spreadsheet allows modifying the properties. Select one or several net names,and a pop-up menu (right click)
15
Create the board outline (Tool Obstacle Select Tool) Place components (footprints) Route those nets (e.g. autoroute) Note Online DRC OFF Note Online DRC ON Check out statistics of unrouted nets Enable a modular group of nets (e.g LCD_Connec) Cleanup design/Design Rule Check Run Post Processor name.bot, name.top, thruhole.tap For all modules Create Reports
16
Check statistics of unrouted nets : Auto Design Rule Check Select All, and Check Detail Obstacle. Cleanup design/Design Rule Check : Auto Cleanup Design Select All, and Check Detail Obstacle. Auto Refresh Calculate Statistics Check out the unrouted nets section. Create Reports : Auto Create reports Check the ”Conns Unrouted” box. in order to see the location of unrouted nets. Autorouting/Manual Route : Auto AutoRoute Board : autorouting Tool Track Select Tool, then use the mouse and right button (select Finish in the pop-up to terminate a track).
17
More detailed description of the previous steps : http://www.ee.oulu.fi/~terva/Embedded2003/bulletin.p hp on ”Intro to Orcad” link. Re-use the proposed example, the pad-to-pad spacing, and other properties/settings have been tested. The design is quite simple : two layers TOP and BOT. THRUHOLE.TAP contains drilling properties/settings. Even better description in the tutorial/help provided in the software.
