I get the following Modelsim error when compiling my design for simulation:
"# ** Error: tx_and_replica.vhd(362): Actual (function call "to_sfixed") for formal "i_x" is not a globally static expression."
The relevant code snippets are:
1) Port mapping: Line 362 is the s_tx_tmr conversion to signed fixed.

How do i find that torque?
A physical correct attempt of torque calculation must contain an expression for angular acceleration. It's till missing from your posts. static friction, as mentioned by erikl is a differnt point, but not directly related to the problem. You can (in principle) design a drive with frictionless bearing, e.g.

I'm working one generating a VCCS in finesim.
The code is as follows :
Videal ideal 0 1
rpolyres ideal 0 50k
gin_current IN OUT pwl(1) IN OUT 0 0 0.1 0 0.2 'i(videal)'
Howere, I always get an error saying 'ERROR! variable in static expression'
I checked the .sp file and find that it is the 'i(videal)' that causes this pro

I'm getting the following error when compiling in ModelSim:
Array type case expression must be of a locally static subtype.
The error points to the first part of the case statement in the following code:

answer is yes and no.
use temporal expression to do that.
assertions are two kind
(static - without simulation ) -which is not possible in specman
(dynamic - while simulation ) - which is very much possible through temporal checks
