-D VCD_OUTPUT unused?

[x8-999-github]

When running simlulation in apio a parameter is given to iverilog. This parameter is later used to determine the name of the output file. On my setup this does not work (and the replacement does not happen with the effect that my test files become VCD_OUTPUT.vcd (including the)

iverilog -B "/home/why/.apio/packages/toolchain-iverilog/lib/ivl" -o leds_tb.out -D VCD_OUTPUT=leds_tb "/home/why/.apio/packages/toolchain-iverilog/vlib/cells_sim.v" leds.v leds_tb.v
vvp -M "/home/why/.apio/packages/toolchain-iverilog/lib/ivl" leds_tb.out

Hi. I have released apio 0.3.4, that uses the stable toolchain. Could you install this version and test it again?

The stable toolchain has Icarus Verilog v10_1, and the latest toolchain (use in apio 0.4.0 beta) the version v10_2. Maybe there is a different in the management of this flag between versions.

Indeed "downgrading" to 0.3.4 solved my problem ! thanks
