As part of recent decisions regarding namespace naming conventions, all namespaces will be changed to snake case. sim_clock::Int became sim_clock::as_int. "as_int" was chosen because "int" is a reserved keyword, and this namespace acts as a selector of how to read the internal variables. Another possibility to resolve this would be to remove the namespaces "Float" and "Int" and use unions instead. Change-Id: I65f47608d2212424bed1731c7f53d242d5a7d89a Signed-off-by: Daniel R.
