CSIX VIP (Common Switch Interface Verification IP)
The CSIX VIP (Common Switch Interface) is a highly flexible and configurable verification IP that can be easily integrated into any SOC verification environment. Supporting UVM, this CSIX VIP is part of the asureVIP portfolio of implementation-proven VIP offerings.

The CSIX VIP can be used for both functional verification and as an emulator and provides the capability to communicate over 32 bit CSIX bus. The VIP comes with a UVM Monitor for checking the conformance of the design with the technical specifications. The monitor performs the protocol checks and reports errors for noncompliance of features with CSIX-L1 bus specification. T&VS CSIX transactor comprises of a synthesizable hardware part written in System Verilog and a software part written in C++ and System Verilog.
