Hello all, I have some questions regarding Synopsys SAED90nm EDK library: 1) Do I have to configure any setups in cadence Encounter to place and route a design using Synopsys SAED90nm library ? 2) What is a Milkyway library ? 3) Is it easier to use Synopsys ICC or cadence Encounter with this (...)
I'm currently working with cadence Encounter. For MMMC place & route it requires "func" and "test" SDCc constraints. After place & route func and test minimum, typical and maximum SDF files are generated. What is the purpose of func and test (...)
Lef is mandatory as it has the size of the cell and the pin locations. If you have gds u can dump out a lef through cadence virtuouso. But lef is a must view.
The cadence SOC Encounter is targeted for RTL to GDSII flow where you start your design with HDLs/SystemC and synthesize to generate/simulate gate level netlist, do auto place & route, to DFM and generate GDSII. This flow always has presence of standard cells to enable all the stuff. The (...)
My experience in in FPGA field, about a year now. I need to learn ASIC tools. I tried finding any good tools on the internet but all of them are commercial (cadence, Synopsis and Mentor Graphics). I could not download any evaluation or demo version of their tools. Some of them have links to request to get an evaluation version of some programs but
Hi, I want to estimate the temperature of a circuit after place and route by cadence SOC encounter. I am able to run some workloads on this tool and extract switching activity and then extract power from synopsis power compiler. Considering these, does anyone know a solution to estimate (...)
ICC is primarily a timing-driven auto-place&route tool for use with standard-cell libraries (sets of pre-made logic gates that make-up a digital design). Everything ICC does is based around this goal - it is not the right tool for custom analog layout of individual transistors, resistors, etc. and for manual design, it's GUI (...)
Front end design means .. Is it a schematic? first make your device size as 3.15 in cadence and then start to place your component and route as the schematic..
Hello I am using the ICstation in my circuit layout . I am enjoying the pick and place function from the schematic to the layout with shorter route suggestion. I would like to ask you if cadence support this feature or not. have a nice day
Hi I have designed my system in Verilog HDL. Can I design Layout in cadence from verilog code ? If yes then kindly mention steps involved too. if any related reading material is available then kindly post the links that will be really helpful. Thanks to all.
Hi, I need to manually add some vias in cadence EDI. I used setViaEdit followed by editAddVia commands. Vias can be added, but not all vias are at the location I specified. What prevents the vias from being added at the specified origin coordinates? Thanks.
I have two important answear: 1. Orcad PCB editor or cadence Allegro have a union functionality how Altium Altium Designer you can place and route a part of the circuit and than I can do a union of this section of the circuit and than move it in the board how a single component. 2. There (...)
Hello, I wonder what commands/methods people use to generate .lib for a design, and use it later for place and route at top level. I am using EDI 9.1, found the timing model commands have very limited documentation in fetxtcmdref.pdf. and I could not get (...)
to do so you need a software to synthesize your code with standard cells,such as cadence PKS_shell then you should do place and route with a software such as cadence SOC Encounter, take a look at this: Tutorial for cadence Build Gates and (...)
Hi I am using SOC encounter for place and route I have synthesized and routed my netlist but in SOC I cant see the internal contents of cells,and cells appear just like black boxes this problem exists when I Import the gds file in cadence Virtoso, I think I'll need some (...)
Hi I'm doing a full custom IC design for digital system using cadence tools. I'm now in the process of doing DRC for my layout and after this LVS. Is it the nest step is doing place and route? and I have no tool that can automated place and (...)
Hi, Say, I have done place & route for my design using cadence/Magma & doing signoff checks now. What are all the things to look for if you see a correlation issue between implementation & signoff tools? Is there any doc/white paper which explains all the key points to debug the issue? Thx Kumar
Dear all i have a problem, i have requested to fabricate a chip with mosis, and i had IBM 0.13 DM cmrf8sf Kit, and i designed my system using encounter SOC as a place and route tool, the problem is that i want to export to mosis the GDS file, BUT the file that i got from mosis was a mapping file for (...)
I am working on analysing the effect of various place and route schemes on the capacitance of a circuit. So,please let me know the different place and route schemes used in cadence Encounter in the order of optimality it provides
Hi, I have used soc encounter for place and route. Now I need to use nanosim for further timing and power simulation. How do I do RC extraction? I know that I can import GDS files into virtuoso and do RC extraction there. Is there any better ways? Thanks very much!
