how to increase blow up limits of a quantity in Cadence VHDL-AMS simulator

hi
Can anyone please tell me how to increase the blow up limit of a
quantity in a VHDL-AMS model.
Thanks in advance.

If you put a "quantity" statement in the analog control file for the AMS
simulation - for example:

//

defineVoltage quantity \
name="V" \
units="Volts" \
abstol=1e-6 blowup=1e10 huge=1e5 \
description="Voltage"

tran tran stop=5u

I tested this by setting the blowup limit to 1, and it fell over with my 5V
supplies.

Why are you getting signals at the blowup level anyway? It tends to suggest
you really have a different type of quantity which is scaled differently, and
you're using voltage (say) to represent that. Or is it that you've defined
your own quantity, and it's picking up the default blowup limit of 1e9?

You didn't give much information.

I'm not sure whether there is another way of doing this for VHDL-AMS. For
Verilog-AMS, the blowup limit is a Cadence-specific option in the files
such as:

<instdir>/tools/spectre/etc/ahdl/disciplines.vams
