Hi,
I'm totally beginner in FPGA board.
My board is Zybo Z7-20
I want to output four digital signals like a=0110, b=0010, c=0111, d=0001 with 200 us period.
Therefore I wrote the code like this :
module gate_signal(a, b, c, d);
output a;
output b;
output c;
output d;
always begin...
Hi,
I want to shift the voltage level 3.3 V to 20 V with FPGA.
Moreover, I want to generate square signal which voltage level is -20 V to 20 V also with FPGA . Is it possible?
Thank you.
Hi,
Like title, I want to use 'time' at model parameter
For example,
.model m1 NMOS(LEVEL = 1 VTO = 'time')
I want to change VTO parameter with time change in transient analysis.
Can I do this?
Can I measure time in HSPICE?
For example,
.model m1 NMOS(LEVEL = 1 VTO = 'TIME')
I want to change parameter VTO if time change in a transient simulation.
Can I do this??
In matlab
expp = (1/2)*exp(Vgt/(Etaf*Vth));
this code works well. The minimum values of expp is about 3.5e-18.
However in Verilog-a, expp values are always 0.
I checked Vgt, Etaf, Vth, and these variables calculated well.
I have no idea What's the problem of this code...
Hi,
I want to calculate ln(1+x)in verilog A. I know that the code is
But if the x value becomes very small(ex x=3.52e-18), the y value becomes zero. In MATLAB, I can calculate like
and I want to calculate like that code. How can I calculate more accurately?
