- 03:00 PM Issue #1474: Document parse-order-dependency for config files
- Creating the testcase shows me that you require an absolute path in the VLT file. Is that by design or a bug?
- 01:43 PM Issue #1474: Document parse-order-dependency for config files

- 12:41 AM Issue #1315: Using an array in a function called from a parameter
- I just bumped into this too. Do you think this is a tractable problem for someone new to the Verilator codebase?
- 10:39 AM Issue #1052 (Duplicate): Localparam array can't be passed into parameter-called function
- bug1315 is the same issue, so tracking there.
