Hello everyone,
I am new to the tool Apache RedHawk. I set up power analysis for Static and Dynamic (only vectorless) mode. But I am facing a strange problem. During Static analysis, I have values of wire & via voltage drops. But, during the dynamic analysis, I have no values for voltage drop maps.

However, the current maps, power density maps, decap maps are working fine.
Does anyone have any idea about where to start debugging?
I am using APL files for both dynamic and static analysis.
Thanks in advance!!
 

Hi

could you upload your input files(included .gsr .lef .def ,... files) that i see what is the problem and help you to solve it.

thank you.
 

Hi,
Sorry, It is not possible for me to share the input files as I signed a NDA. Can you guide me from where should I start debugging. I already looked into the log file. BUt it was not helpful. Any ideas would be appreciated!!
Thanks

it looks like your margins are set as NaN (not a number). I am not sure how you did it. It could be a simple mistake, so the analysis looks like it's all red.
 

Hi, I also saw that a bit later. But I do not know how does redhawk pick up the margin values? Is there any specific keyword. I could not find one in the manual.
 

please do following steps:
step1: check your configuration panel (right of GUI) for margins.
step2: see your .gsr file and check your VDD and GND values.
step3: see your .lef , .def files and check your VDD and GND connections.
