port description

Started by sant...@isac.gov.in August 24, 2006
Hi,
I bit confused with the /port directive in architectural file
(*.ach) ADSP-21020/60 sharc processor. I am using the following lines
in *.ach file

.segment /port /begin=0x00208000 /end=0x00208000 /dm ADCPort /width 16;
.segment /port /begin=0x00208600 /end=0x00208600 /dm ADCMuxPort /width 16;
When i am simulating the code, i am geting the following error
" Port does not exist or is not opened". I think a *.ptr file need
to be created ... can any one help me out..
thanks and regards,
SS
