Floorplanning

  • SOC Encounter :: Layout Routing Issues
    Hi I am facing a problem with the layout generated by Encounter. I am unable to route the design properly. After setting up the Floorplan of the design when I place the Standard Cells, it also routes the metals and the metals are overlapped. Also it doesn't use the standard rules like using M1 Horizontal...

  • Re: SOC Encounter :: LEF File load Failed
    Hi, I found the problem and resolved. Actually I was not using any Floorplanning while taking the pic that I shown before. Now I am facing another problem. I am unable to route the design properly. After setting up the Floorplan the design when I place the Standard Cells it also routes the metals as...

  • Re: pin placement around core in encounter
    Hi, You can use editPin command in way to place IO pins on boundary of the block. Just example from documentation (Encounter Digital Implementation System Text Command Reference): Example: The following command modifies the pins as specified here: - the command runs on the module DTMF_CORE_INST1 - the...

  • How do I control where the routing tracks start?
    I am creating a floorplan in Encounter 9.14-s274_1. I have an updated technology lef and I am regenerating my abutted floorplan. The problem is that I have to maintain the pin locations of the subblocks. The new lef has changed the routing directions of each layer, so M1 went from horizontal to vertical...

  • Managing ECOs in Mixed Signal Designs
    Imagine you are days away from completing the implementation of a fairly complex mixed-signal design, and you are already day-dreaming about the vacation you have planned in a few weeks. Then it happens -- the dreaded change in the design requiring ECOs to digital or analog content, or worse yet, implementation...

  • Proving that a given netlist A results in better layout than netlist B

    Hi, I have a very general question, I have two netlists A & B, basically same functionality but somewhat different synthesis( though mapping to same library) in front end. I need to see which one of them is doing better in terms of layout. What parameters can I use to compare two layouts from soc...

  • Multiple Pin Metal Layer

    Hi friend I need an urgent help in the inplementations of a hierarchical block. In my design i need to use multiple metal layer for a some input/output pins.Presently i am using MET4 for the pins. I need the same pins in MET2,MET3 and MET4. Please suggest the way to impement this in EDIS

  • Mixed-Signal Physical Design Implementation Made Easy
    Getting a complex mixed-signal design assembled and completely analyzed for mask design is a huge challenge today. The IPs are complex and too many decisions need to be made to meet design budgets. All this is not possible with anything less than a fully automated, front-to-back mixed-signal design solution...
