    OrCAD Vs Design Entry HDL ( Concept HDL) Reply

    I am selecting a schematic entry tool for a PCB design that will have high speed serial technology PCIe Gen 3.0 and DDR3 and possibly blind and buried vias.  It is my understanding that OrCad would NOT support the Constraints for HS, although easier to work with, and that Allegro Design Entry HDL is the tool required for these advanced technologies and applications?

    What are the differences between these 2 schematic capture tools? What is the learning curve for an experienced PCB design engineer with Allegro HDL?

    Well this is a pickle...actually its more of a kumquat.

    It's not that you can't draw it in OrCAD Capture it's just that it's much easier in HDL because you get access to Constraint Manager from HDL so you can set the rules in CM at the front end. In Capture you can add some properties to nets but it's much easier to draw the schematic and then netlist and set everything up in Constraint Manager in PCB Editor. The key here is that the level of PCB tools you would need to define the correct rules in Constraint Manager, at least an Allegro PCB Designer license.
