ar How to see placement reasons of cells? How to highlight timing start/end points? By community.cadence.com Published On :: Tue, 23 Apr 2024 13:37:57 GMT I am working with innovus on a huge design. I found some cells are placed far away from both timing start points and timing end points. I suspect some other timing paths may be near-critical that results in this sub-optimal cell placement; or innovus has to place the cell far away due to congestion of placement or routing. Is there a way to see why innovus places/moves the cell during place_opt_design or ccopt_design? Also, is there a way to highlight all timing start points or timing end points that go through a cell? There may be thousands of timing paths through this cell. I tried using report_timing and timing debugger but it is very painful to click the highlight box and highlight the timing paths one by one.

ar Destructive form of "cons" - efficiently prepending an item to a procedure's argument which is a list By community.cadence.com Published On :: Tue, 12 Nov 2024 18:20:40 GMT Hello, I was looking to destructively and efficiently modify a list that was passed in as an argument to a procedure, by prepending an item to the list. I noticed that cons lets you do this efficiently, but the operation is non-destructive. Hence this wouldn't work if you are trying to modify a function's list parameter in place. Here is an example of trying to add "0" to the front of a list: procedure( attempt_to_prepend_list(l elem) l = cons(elem l) ) a = list(1 2 3) ==> (1 2 3)attempt_to_prepend_list(a 0)==> (0 1 2 3)a==> (1 2 3) As we can see, the original list is not prepended. Here is a function though which achieves the desired result while being efficient. Namely, the following function does not create any new lists and only uses fast methods like cons, rplacd, and rplaca procedure( prepend_list(l elem) ; cons(car(l) cdr(l)) results in a new list with the car(l) duplicated ; we then replace the cdr of l so that we are now pointing to this new list rplacd(l cons(car(l) cdr(l))) ; we replace the previously duplicated car(l) with the element we want rplaca(l elem) ) a = list(1 2 3) ==> (1 2 3)prepend_list(a 0)==> (0 1 2 3)a==> (0 1 2 3) This works for me, but I find it surprising there is no built-in function to do this. Am I perhaps overlooking something in the documentation? I know that tconc is an efficient and destructive way to append items to the end of a list, but there isn't an equivalent for the front of the list? Full Article

ar Relative delay analysis is impacted by pbar By community.cadence.com Published On :: Thu, 23 Nov 2023 21:32:03 GMT Does anyone know how to not include a pbar in a constraint manager analysis? I have some relative delay constraints applied on a group of differential nets. When I analyze the design these all show an error. If I delete the plating bar from the design they are all passing. The plating bar gets generated on the Substrate Geometry / Plating_Bar class. I understand that I could just delete the plating bar to verify the constraint but the issue is when I archive this design I would like it to be clean meaning it is in the final state for manufacturing AND passing all constraints according to design reviews. Anyone have an idea? Thank you! Full Article

ar How to avoid adding degassing holes to a particular shape By community.cadence.com Published On :: Wed, 10 Apr 2024 11:47:20 GMT In a package design, designers often need to perform degassing. This is typically done at the end of the design process before sending the design to the manufacturer. Degassing is a process where you perforate power planes, voltage planes, and filled shapes in your design. Degassing holes let the gas escape from beneath the metal during manufacturing of the substrate. The perforations or holes for degassing are generally small, having a specified size and shape, and are spaced regularly across the surface of the plane. If the degassing process is not done, it may result in the formation of gas bubbles under the metal, which may cause the surface of the metal to become uneven. After you degas the design, it is recommended to perform electrical verification. Allegro X APD has degassing features that allow users to automate the process and place holes in the entire shape. In today’s topic, we will talk about how to avoid adding degassing holes on a particular shape. Sometimes, a designer may need to avoid adding degassing holes to a particular shape on a layer. All other shapes on the layer can have degassing holes but not this shape. Using the Layer Based Degassing Parameters option, the designer can set the degassing parameters for all shapes on the layer. Now, the designer would like to defer adding degassing holes for this particular shape. You may wonder if there is an easy way to achieve this. We will now see how this can be done with the tool. Once the degassing parameters are set, performing Display > Element on any of the shapes on that layer will show the degassing parameters set. You can apply the Degas_Not_Allowed property to a shape to specify that degassing should not be performed on this shape, even if the degassing requirements are met. Select the shape and add the property as shown below. Switch to Shape Edit application mode (Setup > Application mode > Shape Edit) and window-select all shapes on the layer. Then, right-click and select Deferred Degassing > All Off. Now, all shapes on the layer will have degassing holes except for the shape which has the Degas_Not_Allowed property attached to it.
