Is there any way that I can synthesis my design using all the 8 synthesis strategies(optimized area, performance...) available in Vivado and have one synthesis report for each? Now the following TCL is the command that starts the synthesis.
Have you taken a look at the ug901, vivado-synthesis documentation?
In there if you look at the details under "Running Synthesis with Tcl", the -directive switch allows you to choose various strategies.
