Experience with Simulating RocketIO in Modelsim

Does anyone have any experience simulating RocketIO in Modelsim SE via
use of SmartModels. I am trying to stimulate the TXP and TXN pins of the
MGT via use of a .do file. Is there are proper way to do this, or is the
following acceptable:

restart -f
force RocketIO_10mhz 0 0ns, 1 50ns -repeat 100ns
run 2us
run 50ns
force RXNIn1_Data 1
force RXPIn1_Data 0
run 100ns
force RXNIn1_Data 1
force RXPIn1_Data 0
run 100ns
force RXNIn1_Data 1
force RXPIn1_Data 0
run 100ns
force RXNIn1_Data 0
force RXPIn1_Data 1
run 100ns
force RXNIn1_Data 0
force RXPIn1_Data 1
run 100ns
force RXNIn1_Data 0
force RXPIn1_Data 1
run 100ns
force RXNIn1_Data 1
force RXPIn1_Data 0
run 100ns
force RXNIn1_Data 1
force RXPIn1_Data 0
run 100ns
force RXNIn1_Data 0
force RXPIn1_Data 1
run 100ns
force RXNIn1_Data 1
force RXPIn1_Data 0
run 100ns

p.s. The input clock to the MGT is running at 40Mhz

Hi Timothy,

if you really want to punish yourself then you can work with the
force-commands.

However, if you want to work with the Rocket-IOs properly then the only
real way is to build a testbench which models your system.

This means:
- create the clock-signals in the testbench
- build a system that lives on itself as far as possible and is not
dependent on force-commands.

Cheers,

Martin
