Im a little confused. If you have a driver/buffer cell driving another cell, it will be something like this:
buffer cell: inputA > buffer > outputX
load cell: inputC > cell > outputD
the load cell, inputC usually has max_transition constraint. If this is not met, we must use a stronger...
didn't do anything :( we are talking about reading in a tech.lef file, you're saying you had the same issue which is track width definitions not be read from the tech.lef by ICC2, but this switch fixed it for you?
Hello,
I have a DEF file, and a tech.lef file (Cadence tech lef format) which contains track width definitions.
Step 1: I'm using icc2_lm (library manager) to read in the tech.lef, write an ndm library. But to do this, I must also read in Synopsys format lef mlikyway techfile.
Step 2: Then using...
I've been told that ICC2 supports OA Cadence format techfile. I have an IP DEF file that was outputted using ICC2, and the designer provided a Cadence OA techfile with it, even though he used ICC2 to write out the DEF.
So my question is, how do I read this DEF back into ICC2 using the...
I am given a DEF, didnt create it myself.
I was able to view the DEF in ICC2. I selected a specific layer (M1), and selected OPC and Area fill shapes. But I dont see any of the FILL shapes. If II select "Fill cell", it highlights the entire cell, and not the shapes inside of it only.
When I...
Hey, thank you.
I just tried it, but I'm only able to get 1 of the total 4 instances of the port locations.
For example, this only returns the locaiton of the first portX instance (out of 4 total):
set port0 [get_ports PclkOut[1]]
set term0 [get_terminals [get_object_name $port0]]
get_attribute...
I am able to read a DEF, and for a given port, I can get its bounding box.
However, if portX appears 4 times, the bounding box definiton is the smallest box possible that contains all these 4 portX instances.
However, I want to get the xy locations of each of these 4 portX instances. How can I...
I want to check if a DEF view matches Layout view (similar to LEf vs. Layout checking), but in order to that, I can think of loading DEF in ICC2, converting to LEF, and then comparing LEf vs. Layout. I have access to Lef vs. LAyout checker tool, but not Def Vs. Layout.
I was able to load the...
