Hi,
You have to set clock frequency in simulation with command line option
-F! Default is 4MHz! And you will get at least a small difference:
simulavr time unit is 1ns and period for 16MHz is 62.5ns!

Attached program send 'A' word an UART(F_CPU=16MHz, Baudrate=9600),
delay between Word 50ms.
Start record, launch:
simulavr -c vcd:tracein.txt:trace.vcd -f uart_clear_c_tx.elf -d atmega16
After that, I view file in GTKWave and Pulseview(Sigrok) [attached image]
Decoded Baudrate = 2400 = 9600/4
And delay between Word 'A' ~=200 = 50*4
Dirty Hack solved this problem, change in VCD file
from
$timescale 1ns $end
to
$timescale 250ps $end
