强度值（Strengths）\\
有强度的网络可以使模块更加精确。\\
\\
语法\\
<code verilog>
( strength0 [, strength1 ] ) | ( strength1 [, strength0 ] ) | cap_strength 
strength0 = highz0 | pull0 | strong0 | supply0 | weak0
strength1 = highz1 | pull1 | strong1 | supply1 | weak1
cap_strength = large | medium | small
</code>
强度表如下：\\
Strength level\\
^ Strength level       ^ Name         ^ Keyword                              ^
^ 7        | Supply drive       | supply0 , supply1                                                      |
^ 6        | Strong drive          | strong0 , strong1                                                            |
^ 5         | Pull drive   | pull0 , pull1                                              |
^ 4         | Large capacitive   | large                                                |
^ 3        | Weak drive      | weak0 , weak1                          |
^ 2          |Medium capacitive    |medium                                      |
^ 1         | Small capacitive    | small                                      |
^ 0         | High impedance    | highz0 , highz1                                     |
