RE: [IBIS-Users] Ground Clamp Reference

Hello, Mei Yee,
 
Yes, this is standard for all of the I-V tables.  It is highly recommended
that all I-V tables should go from -Vcc to 2*Vcc in the completed IBIS
model.
 
More information can be found in the IBIS Cookbook.

When you have completed a model, please feel free to send it to the IBIS
Model Review Committee.

Best regards,
Lynne

	Subject: [IBIS-Users] Ground Clamp Reference
	
	

	Hi all,

	 

	I used s2ibis3 to simulate my Input pad and I realized that the
sweep range for Ground Clamp curves are from -Vcc to Vcc, where Vcc is the
the value for typical. However, this range remains the same figure for ALL
corners i.e. fast, slow and typical. This means that if my Vcc is 3V, the
sweep range for all the corners is -3 to 3V, regardless of my Vcc at various
corners.

	 

	Is this the standard for Ground clamp? I tried using the keyword
[GND clamp reference] 2.7 3 3.3 but the range still remains -3 to 3V.

	 

	Kindly advice.

	 

	Thank you.

	 

	Best regards, 

	Mei Yee
