Hi,
I have a generic defined as a std_logic_vector(31 downto 0). It defaults to all bits being high ("H"). I have a question regarding passing the generics value in modelsim. Is it possile to set only particular bits of the generic? For example, say set only bits 12 downto 10, while the...
Hi,
Thanks for the help. I am facing another problem - Orcad Capture is not allowing me to use Monte Carlo analysis where each run is a DC sweep of a model parameter :cry:
Is there any way I can go around this limitaion?
Thanks,

Hi,
I am using Orcad Capture for simulating my design. I have an opamp based design. I need to find out how the offset voltage of the opamp varies when there is variation in the Vth of the other transistors. Basically, I need to use a distribution, say Gaussian, for the Vth variation of all...
Hi,
I have the following opamp circuit (attached). I would like to calculate the expression for the gain Vout/Vin. An offset voltage is present in the opamp.
The reference that I have sites the Vout as:
Vout = Vin - Vos(1 + R2/R1)
But I am unable to understand how to arrive at this result...
Hi,
I have to find the variation in the output of my design when the vth0 parameter of the mos devices varies. I inserted the required DEV and LOT values in the models and tried doing a MC analysis. The problem I encounter is that each run is a DC analysis of the circuit where one of the model...

Hi,
I have a really basic question.
I have an NMOS transistor whose Id-Vgs curve I have obtained by biasing VDS=0.1 V and sweeping VGS from -0.5 v to 2 V. The threshold voltage is around 1.1 V (its a 5V technology). I need to obtain Ileak from this data. Usually Ileak is equal to Ids measured...
