yes..you can route signal in power layers too. remove power shapes from certain areas and route the signals. But make sure you have at-least one reference plane for all the signals routed in different layers of the board including the signals in power planes. This is to maintain the single ended...
Hi all,
I want to find out the variations in the impedance of a FPC which is run closely and parallel to a stainless steel shield.
The FPC contains a 3 layered stackup as given below.
1. Coverlay
2. TOP Signal Layer
3. Core
4. GND
5. FRClad
6. Core
7. Bottom Signal Layer
8. Coverlay
Below...
Yes.. :)
Also if you are interested you might take a look at this...

Re: I2C ISR(MASTER MODE)
Hi,
Can you re-frame your question :?: and make it a bit more clear..
Do you mean an I2C master with interrupt from slaves. On receiving an interrupt via any of its GPIO pin, the master services the slave. Is this you are asking?
Thanks
Connecting a PIC to USB is not that hard. But it takes time to go through the PIC datasheet and learn USB. I have interfaced a PIC184550 to a PC via USB and had implemented an USB oscilloscope to sample signals upto 40KHz. It was much fun :)
One book i would recommend to get started with PIC &...
hi friends,
i need to simulate the effect of GND vias placed nearby to differential vias in HFSS.
The GND vias are not needed if the differential signals contain purely differential mode only. otherwise for the common mode signals that may be present, the GND vias provide the return path...
I am new to HFSS. I repeatedly get this message while doing a frequency sweep in HFSS.
:arrow: "Adaptive solution setup process hf3d error. Matrix solver exception out of memory. Unable to create child process hf3d. Simulation completed with execution error on server. Local Machine."
The...
hi all,
how can i get the characteristic impedance of a differential line/ differential via from HFSS. Z11 parameter gives you open circuit input impedance. Zot shows the port's terminal impedances.
Or should i have to run two simulations for two models (one with open circuited traces and...
hi..am just beginning to learn HFSS.
I have to model differential vias and need to know at what separation the GND vias need to be added for the return path.
I have simulated the example project "differential vias" given in viawizard 3.1 folder.
But when i plot the E fields over the traces and...
