As you wrote TLM is SystemC based. It means when you write TLM based model you use SystemC library functions.
It is based on OpenSource library and can be run with free tools like Visual Studio Express Edition. So, if you need practice in writing and simulating TLM based model I can help you to write one step-by-step.
well i have a simple counter which c++ based could you help me to make it systemc and tlm based..

As I wrote inside cpp files I used SystemC_Win for SystemC model compilation. Now I checked under Linux.
You should change the following code in 'cnt_sc.cpp'
stimulus_inst.clk(clk.signal()); -> stimulus_inst.clk(clk);
counter_module_inst.clk(clk.signal()); -> counter_module_inst.clk(clk);
sc_start(clk, -1); -> sc_start();
I just clear counter at some random time.
