I tried another way.
In paramset I set reltol=0.01, vabstol=1e-5, iabstol=1e-11 for time from 0 to 300mS,
then they2 should be changed to 0.0001, 1e-7 and 1e-12 from 300mS.
First it inform me about option setting to reltol=0.01, vabstol=1e-5 and iabstol=1e-11 and than
"FATAL (CMI-2002). Insufficient memory available. To reduce memory for rf analyses, please refer "aps -h rfmemory""
When I changed these options to default 0.001, 1e-6 and 1e-12 simulation start running without any error message.
I am confused. I thought just opposite: more tough options need more memory
