Signal Strength %v

Hi,

How to use signal strength (%v) in verilog.

Hi Jatin,

You can use %v same as %b or others. It reports strength of a net but only in a scalar type. Three characters represent the strength, which is displayed in the console. The first two characters inform us about strength and the third character is the actual value of the net. In Verilog there are only four values: 0, 1, x, z, but the value returned by %v can also be L or H. See the table below for a full description of the strength identifier:

Mnemonic	Strength name	Strength level
Su	Supply drive	7
St	Strong drive	6
Pu	Pull drive	5
La	Large capacitor	4
We	Weak drive	3
Me	Medium capacitor	2
Sm	Small capacitor	1
Hi	High impedance	0

The third character:

0	Logic 0 value
1	Logic 1 value
X	An unknown value
Z	A high impedance value
L	Logic 0 or high impedance value
H	Logic 1 or high impedance value

Hope you get your answer.
