VCS_HOME should be set appropriately based on the environment. What does it means?

I didn't understand how to change the environment variable as mentioned in in the integration module. What is VCS and what VSIM?

I run ./tools/bin/tmake without changing any macro and got an error. error details from the build log is attached below.

If you have Synopsys VCS tool, go to tree.make file and change the the following variables to the paths of tool on your PC: VCS_HOME := /home/tools/vcs/mx-2016.06-SP2-4 NOVAS_HOME := /home/tools/debussy/verdi3_2016.06-SP2-9 VERDI_HOME := /home/tools/debussy/verdi3_2016.06-SP2-9

vsim is the executable present in the VCS tool directory which runs the simulation. To build the verilog modules, run this command: ./tools/bin/tmake -build vmod. There is no need of Synopsys VCS for this.

okays thanks, I have done that and have generated Verilog files. But there is an issue while compiling the code in Quartus and I am getting some error saying that $RollPLI is a system function and cannot be synthesized.

Actually, I am following a master thesis (https://lup.lub.lu.se/student-papers/search/publication/9007070) and trying to create IP for NVDLA core. it is was mentioned in the thesis page 45(28) table 3.1 (verilog Macros), that some macros listed in the table should be defined in the include file to get rid of some error. I didn't quite understand those macros, Could you kindly look into those.?

[rookie0620]

can i ask a question about how do you solve the error that $RollPLI is a system function and cannot be synthesized, there are plenty of $RollPLI in files

[qaziullah]

@rookie0620 you have to define the macros given in the thesis file file linked above.
