I guess that wipro and hcl are companies in India. I don't know how the business inside these companies is going, However in general Cadence, Mentor Graphics and Synopsys are the dominating companies for Electronics Design tools.
You can recognize that each company is providing tools for each design level. For RTL level you need tool for design abstraction and tool for simulation or verification.
I worked more with Mentor Graphics tools, so I can tell you what tools are used for that purpose. For design Abstraction, they have HDL Designer. For Verification, they have Questa.
