[SI-LIST] One strange question on my Hspice simulation!

Hi all,
I want to estimate one p2p net with Hspice, the structure is simple p2p net
like as following: IC_buffer_output <--> transmission line <--> IC_buffer_input.
After I finished the whole structure, one strange question appears when I
running the *.sp file. The error note given is as following: BSIM3 Fatal
**error** Effective channel width <= 0.
I can't find what is wrong with the file, so I do some test through cutting the
path as following 4 steps: (1) cut the connection between buffer_input and
transimission line; (2)add one C_loading to the end of transimission line and
run the simulation, the result is ok; (3)stimulating the buffer_input directly,
it works also rightly. (4)However, as described before, when I connected the
whole channel(buffer_output + transimission line + buffer_input), it doesn't
work.
Appreciate your advice very much! Thanks firstly!
Best Regards!
Stephen
