In general, pin numbers are not shown on discreet symbols, whereas they are shown on connector and IC symbols.
I need a Mentor Graphics tutorial!
Pin connection points are determined by where the pin meets the symbol outline border. Active low input or output. Pin Names will not always be shown, depending on the type of symbol.
Negative Logic Pins Negative logic pins are displayed with the use of overbars in the pin name.
Pins can be of any length, and rotated to any orientation, but the connection point remains where the pin makes contact with the symbol outline border. No implicit pins are utilized for these functions. This outline appears as a dxdesigne box surrounding the symbol during symbol editing.
All power, ground, and no-connect pins are explicitly shown on symbols. All of the pin settings must be considered: Pin Text Pin names should all be unique, duplicate pin names are not allowed because pins cannot be mapped in the layout tool if there are two pins with the same name.
Active high clock input or output. They are shown on IC symbols.
DxDesigner Tutorial: Schematic Symbol Pins
Negative logic pins are displayed tutotial the use of overbars in the pin name. While having appropriate labeling and naming for schematic symbols is the most critical aspect of organizing your symbol library, ensuring that pins for all symbols are consistent is equally critical.
Schematic Symbol Pins Tweet.
Pin Types are always invisible. Clock pins are normal pins, with a clock graphic. Pin names should all be unique, duplicate pin names are not allowed because pins cannot be mapped in the layout tool if there are two pins with the same name.
Optimum recommends a 0. Pin Numbers will also not always be shown, depending on the symbol.
Optimum maintains rigorous standards for pins on schematic symbols, let’s take a more in depth look. Normal and inverted pins consist of the pin only, with no drawn graphics used. Pin Connection Points Pin connection points are determined by where the pin meets the symbol outline border. Optimum Design Dxdessigner Blog. Active low clock input or output.
Even tutoria, pins perform the same function ground connection, no-connects, etcthe names must still be unique. Active high input or output. Power, Ground, and No-Connect Pins All power, ground, and no-connect pins are explicitly shown on symbols. Selecting Invert Pin from the same dialog will give the pin a dot pin. Generally speaking, pin names are not shown on discrete, connector, or logic gate symbols.
