You can use the following to read your into a variable D.

fid=fopen('silicon_simr1.txt');
fgetl(fid)
VarNames=fgetl(fid);
strsplit(VarNames)

c=1;
while true
    data=fgetl(fid);
    if data==-1
        break
    end
    D(c,1:2)=str2num(data);
    c=c+1;
end

This data file is tricky because of the unique combination of delimiters. It does use a simple tab or a fixed space.

I was able to import the data using the MATLAB import Data GUI:

I found that a combination of two custom delimiters acting as a single delimeter worked best (three spaces: 'SpaceSpaceSpace' and five spaces:'SpaceSpaceSpaceSpaceSpace'):

You can either import your data directly through the GUI or use it to create a script or function. I've attached a function which was created by MATLAB which should work for your data.

Here is a plot of the data for verification:
