Just a very quick post this week on a simple, but elegant new SPB16.3 feature for the Allegro Design Entry HDL product.
Prior to the SPB16.3 release, Design Entry HDL (DEHDL) did not have the capability of drawing a new wire from an anchor point of an existing wire. Introducing the anchor point wire stretch will give an extra ease of use factor to the way the wires are connected in the schematic.
You can stretch a wire in any direction, but only from the free end from the anchor point. When you select a wire and click and drag it from its anchor point, a new wire is drawn from that anchor point. Effectively, the wire command is called when you click the anchor point of a wire stub and drag it. For example, in the figure below, three wires are stretched from the free-end towards the right, top, and bottom directions, respectively.
When you select a wire stub to move it, only that stub moves. The other wire stubs or components connected to it do not move. For example, if the selected net, NET2 in the figure below, is moved towards the top or bottom directions, only the wire segment moves in the respective direction. New wire segments are added to preserve the connectivity.
Note: The Wire Selection and Anchor Point Stretch functionalities mentioned above are available only in the DEHDL Windows mode.
Please let me know how you like the new SPB16.3 features for DEHDL.
