nv small with *_DATA_TYPE_INT16_FP16 Error

[nsherer]

Hi,

Trying to generate an nv_small design with both:

define FEATURE_DATA_TYPE_INT16_FP16

define WEIGHT_DATA_TYPE_INT16_FP16

but receiving the below error:

ERROR: eperl: eval: my $i; for($i = 0; $i < 32; $i ++) { $b0 = 16 $i; $b1 = 16 $i + 15; print "assign wt_nan_mask[${b1}:${b0}] = {16{~wt_fp16_nan_flag_w[${i}]}};\n"; } print "\n\n";

error: Global symbol "$b0" requires explicit package name at (eval 41) line 3, line 994. Global symbol "$b1" requires explicit package name at (eval 41) line 4, line 994. Global symbol "$b1" requires explicit package name at (eval 41) line 5, line 994. Global symbol "$b0" requires explicit package name at (eval 41) line 5, line 994.

Why is that?

[huangwei858]

You have to check eperl script settings about your error. nv_small should be set as correct settings or modify reference perl script base on you requirements.

[nsherer]

Can you please provide such script. we would like to have the below confs, please try to compile it and let me know where am I wrong, Should be very simple - only enlarged the width of the DATA/WT to 16 bits

Thx

Doesn't nv_small only support INT8 configuration?

[nsherer]

Hi,

We overcame that issue. modified the small to support also INT16.

Thanks anyway, Neta

How, if I may ask?

[nsherer]

Just used the supplied scripts and modified it accordingly.

[shazib-summar]

Bro, I'm working on a different project now. Thanks for replying though.

Hi, @nsherer What the branch did you use ? I notice that the master branch project.spec can only support int8 feature/weight datatype rtl generate. But the nvdlav1 branch can not generate fpga ram dir.
