In this case, the crosshair will automatically be attached to the grid intersection point, which is less than 1mm away. For example, the Snap Grid is configured at 2.5mm and the Snap Distance is configured at 1mm. In certain cases, the Snap Distance value can be reduced (1/2 or 1/4 of the Snap Grid size), but it should not be larger than the Snap Grid size. In most cases, the Snap Distance value must be equal to the Snap Grid size to avoid placing objects outside of grid intersections. The General section of the Properties panel also allows you to set the Snap Distance at which the cursor will be automatically attached to the anchor point. With the left mouse button select from the menu Options Sheet or chose from the main menu Design Options Sheet Options Tab. If you have your Designer set to Defaults you will have as a title a default Altium sheet with the black logo. We recommend using a smaller grid size (e.g., 1mm) to draw the component symbols more accurately and precisely, and 2.5mm or 5mm grid (depending on the density of the schematic component placement) for the component placement and connections. Firstly open a new empty schematic document File New Schematic. The current grid size can be seen in the lower-left corner of the design space. The type of grids used depends on the unit of measurement selected in the Properties panel. You can set your own values on the Schematic - Grids page of the Preferences dialog (accessed by clicking the icon at the top right of the design space then navigating to Schematic > Grids). Right-click in the grid list of the measurement unit you need. The Netlister will evaluate the formulae in the sub-circuit definition using the default parameter values, as defined in the 10TO1.ckt file.By default, Altium Designer has preconfigured snap grids with 1mm, 2.5mm and 5mm grid spacing, which can be switched in any editor by pressing the G hotkey button at any time.

You can pass design data back and forth between the PCB and schematic this makes many design tasks simpler and more productive.

The default parameter values are listed in the. Altium Designer is the only PCB design software package that is built on a unified design environment, which allows you to easily import a schematic to a PCB layout as we’ve shown here. You can view the content of this file for the model specified on the Model Kind tab of the Sim Model dialog, by clicking on the Model File tab at the bottom of the dialog. To check the default values of a transformer, open the appropriate sub-circuit (. Entering a value for a parameter on the Parameters tab of the Sim Model dialog will override its specified value in the sub-circuit file. Generally you do not need to change this value. The default should be applicable to most simulations. It is a complex device and, as such, is defined using the hierarchical sub-circuit syntax.Īll of the parameters will normally have a default value assigned. Resistance of secondary winding (in Ohms).Ī transformer is not one of the built-in SPICE engine models. To access this dialog, simply double-click on the entry for the simulation model link in the Models region of the Component Properties dialog. The following component-level parameters are definable for this model type and are listed on the Parameters tab of the Sim Model dialog.
