I made a pad ring around each blocks to make it simpler for sroute to connect to. It didn't work though.
After giving up with sroute, I decided to connect the two pins using addStripe instead. However, the stripes don't connect to the rings even though the LEFs don't have any obstruction on any...
I am doing a P&R with two custom LEF files. Both these LEF files have a special power pin called MYPOWER that are connected in the encounter as follows:
globalNetConnect MYPOWER -type pgpin -pin MYPOWER -inst INST1
globalNetConnect MYPOWER -type pgpin -pin MYPOWER -inst INST2...
I am trying to run lvs on a schematic with an instance of a block which does not have schematic view. It has layout+symbol views. However, the schematic is in a .cdl file. Looks like cadence cannot generate the schematic netlist because :
"Missing or incorrecto master.tag in library...
My geometry consists of two thin-sheet coils(mm-sized) buried in dielectrics that are separated far from each other(1cm+).
I tried specifying some mesh operations to help it in meshing the structure, but it still gave me the same error.
OK, now it doesn't simulate at all. Can you tell me how I can overcome the following:
"Surface Recovery failure Possible reasons : (1) . model has multiple objects with thin layers (2) complex model with object overlapping (3)" True surfaces are skewed "

1-fF is a really small cap in those processes. Your logic cap and more importantly wire caps are in the same order. So, make sure you don't lose tunability
with an airvolume width of 2cm:
separation = 0.5cm ->OK
separation = 1.5cm ->OK
separation = 4.5cm ->Does not even simulate, it encounters some problem while meshing and says it might be because of skewed thin surfaces
Increasing airvolume width to 1meter does not help at all
I've used hfss to simulate an on-chip inductive coupling link at 433MHz. Everything was perfect and the results were close to the values I got from ASITIC. I saved separation as a design parameter and changed that from 1cm-10cm accordingly and everything looked fine in 3D view.However, when I...
Hi all,
I've been trying to simulate a simple differential LC oscillator, the one that is explained in Spectre PSS tutorial. However, it gives me positive phase noise at low frequency offsets(~ +50dBc@10Hz), (it gives acceptable negative phase noises for high frequency offsets: -130dBc@1MHz...
