Dear sir,

I follow this instruction about Occamy: https://github.com/pulp-platform/snitch/...tem/occamy

However, when I ran command: make bin/occamy_top.vlt, I met this error:

%Error-PKGNODECL: occamy/snitch/hw/vendor/openhwgroup_cva6/core/include/ariane_rvfi_pkg.sv:20:17: Package/class 'riscv' not found, and needs to be predeclared (IEEE 1800-2017 26.3)

I recognize that your work-vlt/files lacks included file (it doesn't have snitch/hw/vendor/openhwgroup_cva6/core/include/riscv_pkg.sv so the simulator can not find package 'riscv') but whenever I ran the command above, work-vlt/files is automatically generated and it still remain lacking information.

How can fix that?

Many thanks

Hi Nils,

I have pulled new revision. However, I found this error when ran command make bin/occamy_top.vlt: 

verilator_bin: ../V3Ast.cpp:1144: void AstNode::v3errorEndFatal(std::ostringstream&) const: Assertion `0' failed.
%Error: Verilator aborted. Suggest trying --debug --gdbbt

I have installed the correct version of Verilator 4.100 followed this link: https://pulp-platform.github.io/snitch/ug/setup-iis/

How can I fix that? 

Many thanks
