Problem with stopping at smbol level will be that you will not verify the core layout vs schemastic just ios. I believe calibre has chance of defining macro cells which will do the trick
Hello everyone, I'm a newbie in IC Design especially in using Synopsys tools I am working on my design at chip-level using ICC. Hope someone could help me. I want to assign and connect my design input and output ports to corresponding pad or IO cells surrounding the core. How do i do it? :-( Does the layout window (gui) provide a feature t
I dont knw abt the UMC , but for TSMC . wen you load both kind IO's into encounter. you can definitely see difference in the lef definition, Normally for a Core Io , pins are defined and wen you enable instance pin option in encounter you can see the metal pins on these core pads but not on IO pads.

Hi, I am drawing the layout for my design using IBM 0.13um CMOS technology (virtouso). This is my first time using the IBM process so I have a few questions about the layout drawing. 1/ what is the different between pin and pad? When I insert input and output pins in my layout, the LVS can recognize them as IO Ports. (...)
Hi, I am a student working with AMS Hit-Kit V4.0 for a digital IC design. I have simulated the pre-layout netlist with NCVerilog and found the simulation was fine. But the post-layout simulation, which includes the Input and Output pads, shows the input signals fed into the INPUT pad comes out on the other side of the (...)
Hello all, I am doing the layout of Power supply pad for VDDPST supply (I have 2 supplies VDD and VDDPST of 1.8v and 3.2v). This pad is used to supply power to the IO's. For this i have used N-type diodes and one MOSCAP (NMOS cap) as shown in the screenshot. As per my understand, # When some -ve voltage comes then NMOS is OFF (...)

open the pad Cell GDS in layout viewer, then you can measure it. or see the IO pad spec. doc
What program you use? - IC Station? add io ground and vcc pads as cells.. Are you read thies manuals $MGC_HOME/shared/pdfdocs/... ?
Now IO pad will be added in layout's software if I am not wrong. In the past, we extract digital circuit then place IO pads in some layout software. Thus DC's insert_pad has never been useful.
It is better to get it from TSMC. Its IO cell proves good ESD and ESD under pad is very area-saving.
I have a circuit that some devices terminal(D) connected to pad and they are not in I/O, now some question need you help ASAP.? thanks! 1. These device should be layouted to ESD device or normal device? 2. If these device must follow ESD rule, how i care about match issue?
Hi, Sould i insert metal fill at the end of my design? Can anyone give me a layout picture which includes io pad which will be taken to gds2. I need this to compare with my design. Thanx
Hi Siva, I am confused. I thought IO pad design is analog, and should be designed in transistor level, and layout is custom crafted. If you are talking about logic squeeze into the pad then it is digital design, and has llittle to do with IO pad. I am interested to learn what is you job scope. Regards, Eng Han
Teddy: you said that just use last u mean that in the layout,do not full of the pad with each metal just as usually we do,in order to reduce the capacitive load? but i wonder that for the pad the most of the load of it is the ESD circuit,so maybe i have to make the ESD device smaller size. another question is that if i can accept
Hello everyone, I am new to IO pad characterization and hence what should I learn first so it would be helpful in later stages. Regards sandysuhy
There is parasitic diode on the layout because of some active region and/or n-well region and therefore Assura marks it as an error when it checks it. Or ESD pad has a diode which is not mentioned in schematic or something like...
Usually the foundry will provide you the layout and schematic of your IO pad which is actually two diodes.
