Hi All,
I had a question regarding eye diagram in Awanwaves. I am not able to get a
clean eye by using the following code
************Eye Diagram for Awaves************************************
.param per = '480e-12' $desired eye diagram period
.param tsi = '4.8n' $desired eye diagram start time.
.probe tran
+eyetime1 +par
('.5*(sgn(TIME-tsi)+abs(sgn(TIME-tsi)))*(TIME-tsi-per*int((TIME-tsi)/per))')
* Bit time and rise/fall time
.param period = '1/6.25g'
.param trf = 50p
[cid:image001.jpg@01CC269B.4CD81E00]
Please suggest me how to get a clean eye.
Thanks in advance,
Tanveer
