Re: Quatus 10.1 Exception on Deinterlacer Elaboration

Altera_Forum · ‎02-22-2011

Hi,

I have a fairly complex SOPC system which includes a motion adaptive deinterlacer. The SOPC system generates without errors, but when I compile the project, I get the following exception:

Error: IP Generator Error: Exception during elaboration of alt_tapped_delay: java.lang.NullPointerException

Error: IP Generator Error: Please forward the complete log file (including the following stack trace) with your bug report:

I am using Quartus 10.1SP1 and I am targeting the EP4CE40F23C6 device. I have compiled the system for the Cyclone 3, also using Quartus 10.1, without any problems. Has anybody seen something like this or know how I can get past it? I guess I have to go to Altera Support with this...

you might try 10.1sp1 to see if someone has caught the issue before you, or else file a Service Request

Hi,

I forgot to mention that I am already using 10.1SP1. I did file a service request.

I actually need to get an urgent, accurate resource usage for the Cyclone IV device. I need to decide between a C40 and C55, which has a significant cost impact. The Cyclone III and IV are so nearly identical that I guess I could use the CIII results. Final product will have to be on a CIV, so I do need to get the problem fixed at some point.

Anyway, not much I can do but wait for an answer from Altera.

Regards,

Niki

you should explain that point in your SR

i agree that you should get a pretty clear picture from a CIII resource count and then verify whether a 4C40 will work or not

Hi,

I got a response from Altera that it is a known issue for CIV and Stratix V. It will be fixed in the next release. Hope it is not too long from now...
