I've been using the Allegro Design Entry Cis for quite some time but now the company decided to start using the Design Entry HDL, so we could take the advantage of using constraint manager rules directly on the schematic.
I already found out how to convert capture libraries using the Librarian Expert, but I still have some doubts about the usage of the program:
1) How do I add the converted libraries to the schematic? When I try Component/Add... there is no option to add a library to the existing set.
2) Is there a way to have a sort of part manager on HDL? On CIS, I used the part manager to add components already containing informations like spice model, footprint, description, datasheet, etc, using a database. This would be really helpful.
3) On the capture, when I click a certain component to add it, there a preview showing the schematic symbol. That is helpful when I'm looking for a generic symbol. On HDL, there are only some text informations showing. Is there a way to show a preview of the symbol?
Thank you very much for your attention.
Start a DE HDL project through the Project Manager, the "Setup" option allows the libraries to be configured.
For "regular" HDL users, PTF, Part Table Files, are the "same thing" as the CIS database.
IF you don't have any PTFs, you only get the option to pick the Symbol from the library, IF you have PTFs, when you pick a symbol, you get a list of specific values to pick, select one of those and you get the Symbol and Footprint view, similar to the CIS Explorer view.
CIS is based upon the idea of "personal productivity", you, the user, get to do whatever needs to be done, as you go. The HDL flow is for a "corporate environment", "someone else" sorts out the libraries and standards and you, the user, just make use of them. For a single user, the HDL environment takes a lot more initial setting up than the CIS environment requires. About the same amount of effort is required in total but the CIS flow allows this to be "as required" rather than "at the start". Once everything is setup, there is not much to choose between using the tools.
1) You add new DEHDL libraries to your project using the Project Manager Setup form. You'll see a list of available libraries and you can add/remove and from the active list.
2) A similar Part Manager exists for DEHDL. It's used to show which (if any parts) are out of sync with the corporate libraries. I think what you're looks for is the Component Browser - it will show similar data like Capture-CIS when adding a part.
3) The Component Browser in DEHDL will show the relevant Part Table Row property data, the symbol graphics and the Allegro PCB Foorptint (if one has been associated).
Joao DemierI've been using the Allegro Design Entry Cis for quite some time but now the company decided to start using the Design Entry HDL, so we could take the advantage of using constraint manager rules directly on the schematic.
Did the same person who made that choice understand the time that would have to be added to building all of the tools and files needed to really use DE HDL? I've been on Cadence since '93 and would never switch based on that reason. OrCAD allows 90% or more of the properties to be injected directly on the schematic using the property editor. The last few probably need to be done at an Allegro workstation anyway so intelligent choices can be made. Sigh...I feel your pain!
