Active Texts: The Swiss Army Knife of the schematic editor SLED!

July 03, 2015

It is commonplace that suppliers of EDA simulators allow configuring the testbench from some schematic editor. Meanwhile, a gap in terms of functionalities remains between configuring the testbench from the schematic versus from the simulator control file. To fill this gap, and to avoid restraining simulator usage without losing the focus on the schematics, Dolphin Integration provides the “Active Text” feature, an elegant approach to defining smart simulation features inside the schematic editor SLED™.

SLED allows circuit designers to perform graphic entry and to configure their designs in a shorter time. The flexibility of SLED enables the design of true mixed-signal circuits as well as multi-level and multi-physics systems.

In order to facilitate development, SLED 2.3 notably improves the capability of the schematic editor interaction with the simulator through “Active Text”: a symbol placed on the schematics suffices to insert text into the control file. The multi-purpose nature of such an “Active Text” provides any functionality accessible through the netlist. The four main assets of "Active Text" are:

  • Flexibility: eases the development of multiple testbenches by defining relevant directives at the top of the netlist or inside sub-circuits.
  • Multi-language: allows advanced users to add “Active Texts” in any language and to activate these texts only when the schematic is netlisted in a specific language.
  • Productivity: in combination with "Back Annotation" and "Automatic Calculation", speeds common design development by avoiding going back and forth between the simulator and the schematic editor.
  • Adaptability: enables adding specific directives to the schematicfor third-party tools such as layout editors or synthesis tools.
